This question already has an answer here:

It's the time of the year again, namely it is December 2013, and so we shall now refresh our Community Promotion Ads for the new year.

What are Community Promotion Ads?

Community Promotion Ads are community-vetted advertisements that will show up on the main site, in the right sidebar. The purpose of this question is the vetting process. Images of the advertisements are provided, and community voting will enable the advertisements to be shown.

Why do we have Community Promotion Ads?

This is a method for the community to control what gets promoted to visitors on the site. For example, you might promote the following things:

  • the site's twitter account
  • useful tools or resources for physics research
  • interesting articles or findings for the curious
  • cool events or conferences
  • anything else your community would genuinely be interested in

The goal is for future visitors to find out about the stuff your community deems important. This also serves as a way to promote information and resources that are relevant to your own community's interests, both for those already in the community and those yet to join.

Why do we reset the ads every year?

Some services will maintain usefulness over the years, while other things will wane to allow for new faces to show up. Resetting the ads every year helps accommodate this, and allows old ads that have served their purpose to be cycled out for fresher ads for newer things. This helps keep the material in the ads relevant to not just the subject matter of the community, but to the current status of the community. We reset the ads once a year, every December.

The community promotion ads have no restrictions against reposting an ad from a previous cycle. If a particular service or ad is very valuable to the community and will continue to be so, it is a good idea to repost it. It may be helpful to give it a new face in the process, so as to prevent the imagery of the ad from getting stale after a year of exposure.

How does it work?

The answers you post to this question must conform to the following rules, or they will be ignored.

  1. All answers should be in the exact form of:

    [![Tagline to show on mouseover][1]][2]
    
       [1]: http://image-url
       [2]: http://clickthrough-url 
    

    Please do not add anything else to the body of the post. If you want to discuss something, do it in the comments.

  2. The question must always be tagged with the magic tag. In addition to enabling the functionality of the advertisements, this tag also pre-fills the answer form with the above required form.

Image requirements

  • The image that you create must be 220 x 250 pixels
  • Must be hosted through our standard image uploader (imgur)
  • Must be GIF or PNG
  • No animated GIFs
  • Absolute limit on file size of 150 KB

Score Threshold

There is a minimum score threshold an answer must meet (currently 6) before it will be shown on the main site.

You can check out the ads that have met the threshold with basic click stats here.

Is Community Promotion Ads still on? Can I use it if I have a science-y Area51 propodal to promote? – Krumia Oct 13 '14 at 4:51

Yes, they're still active, and will still be active until December when the next thread goes up. You can propose an ad for a proposal but I'm not the person who you'll need the approval of - it'll be your peers who will decide by voting whether or not they'll have the ad fly. – Grace Note Oct 13 '14 at 11:36

Great idea. Not enough folks know about this. I was really surprised when I learned about it months ago. – Brandon Enright Mar 2 '14 at 3:58

@Brandon for the record, I'm dead sure this isn't an original idea. I've seen this somewhere in the community ads of some other site of some unspecifiable year, but I can't quite place it at the moment. The design, on the other hand, is original and fresh out the oven. – Emilio Pisanty Mar 2 '14 at 4:35

Huge thanks to rm -rf, from Mathematica.SE, for building the MM.SE version of this dynamic ad, and porting it for Physics. Image is a retina display (440x500px) and should work fine. – Emilio Pisanty Mar 8 '14 at 22:27

“Nuclei and electrons ⇒ chemistry” is a blatant overgeneralization. There are some question involving atomic orbitals (such as magnetic moment of an atom) that are exclusively physical. I also can point to a physical question about π bond. – Incnis Mrsi Aug 22 '14 at 7:40
    
@IncnisMrsi of course, this wasn't meant to be an exhaustive ad. And SE sites can have scope overlap. – Manishearth Aug 22 '14 at 7:55

The size is important. The images are 'reaped' automatically by the system, and images with the wrong size will be rejected. Nice one, though! – Emilio Pisanty Dec 10 '13 at 20:48

This is nice, but it's a little funny when it says there are no bounties. Maybe it can be customised to only display when there are at least a few bounties, say 100 rep or more, or `150. – centralcharge Dec 28 '13 at 10:16

@GraceNote, is dimension10's idea feasible? – Emilio Pisanty Jan 18 '14 at 18:49
    
@Emilio We can't configure the ads system on our end to display based on bounty status - this is a user-made widget so making special effects for empty bounty status is up to the creators to design. – Grace Note Jan 19 '14 at 13:42

I know we already have one arXiv ad - to which I just proposed a modification - but I'd still like to propose this. The arXiv does not normally push for researchers to upload, but I think this is innocuous enough. It is actually primarily aimed at non-researchers, to help bring home the message that the arXiv does have a huge chunk of the world's physics papers in it. – Emilio Pisanty Dec 11 '13 at 14:28
    
Source is a Fireworks PNG so it's actually an editable vector image if you can get at the proprietary vector layers. (Same for the other one.) – Emilio Pisanty Jan 17 '14 at 14:08

+1 From me too! It is a great website, and I hope there can be some mutual friendliness between the two sites. I don't really understand the "you're either with us, or against us" mentality some people seem to adapt. – Hunter May 12 '14 at 23:44

@Hunter personally, I can't support a site that has no expectation of civility. Just be sure you're not seeing that mentality where there is actually something more going on. – David Z May 15 '14 at 5:20

To add some transparency to the downvotes, I am one of them. I have indicated a willingness to discuss this in an appropriate space on this site (i.e. chat) but the Physics Overflow organizers did not really respond. – Emilio Pisanty May 23 '14 at 16:01

I must say that I feel they responded very badly to the accusations of phishing on this thread (some comments now deleted). I am also not happy that, for a site that would like to be considered as a professional forum, their users list shows me as an active user and therefore makes it look as though I endorse it regardless of whether I do or not. (I also wonder what e.g. Gil Kalai thinks about that.) It is not clear from the outside what the formal moderation is but there are a few big red lights for me. – Emilio Pisanty May 23 '14 at 16:04

@EmilioPisanty thanks for catching the typo. Personally, I was rather appaled about the moderators reluctance (it took them about a week to delete the very inappropriate meta post) in dealing appropriately with the throwing around of very bad (including statements about criminal intentions) accusations of a particular user in the course of the "Phishing Affair". Happily this bad episode is now over... If you read the user profiles you can clearly see who is active and who is not, and when looking at the posts and comments you can discern the imported ones by the attribution line. Peace now... – Dilaton May 23 '14 at 18:41

To be clear, I do not think you addressed the serious and valid concerns on phishing in any meaningful or positive way. And unless you gray out the inactive users' profiles in a visible way on the users page, I will continue to not thank you for using my name without my consent. Ultimately, though, it is up to you - just don't stand and wonder why there's a lack of support from this community. – Emilio Pisanty May 23 '14 at 22:23

@DavidZ Most of the users just want a good site where they can ask questions and get answers; PhysicsOverflow is just another one, and we should appreciate their effort. ِSome users had problems with them when they were trying to change the atmosphere of this site. But now they're gone and have built another site. I really can't see what's your problem now ! – Mostafa May 31 '14 at 9:56

@Mostafa no, just because Physics Overflow exists doesn't automatically mean we should appreciate the effort put in to make it. I've already said why I don't consider this particular site to be a good use of our ad space. – David Z May 31 '14 at 12:18

I am indifferent to “civility wars” that happened here long before me, but this splinter group is dysfunctional as a community. They do not want to think, they only try to rise their self-esteem by mutual admiration. A doomed site IMHO. – Incnis Mrsi Aug 21 '14 at 20:12

@EmilioPisanty Yes, it is running. Have an example at arxitics.com/reviews/1 The website is still under construction and there are only a few users. – soliton Oct 21 '14 at 12:53
    
How about Read, explore, review and discuss preprints and papers? – Emilio Pisanty Oct 21 '14 at 12:57
    
@EmilioPisanty Registered users can subscribe, bookmark, review eprints. This part is almost complete. The reviews section can also used to discuss eprints. Currently, we are working on the exploring functionalities. – soliton Oct 21 '14 at 13:00

I find it a bit hard to navigate the site - I'm never sure whether the section is running or whether I've messed up. (e.g. Explore → Reviews tab → Active tab produces an empty page - presumably not quite the desired behaviour?) Do you have a log with a description of what's running and what's not? That would be nice to have while there are still large parts under construction. – Emilio Pisanty Oct 21 '14 at 13:00

@CrazyBuddy A number of people have been quite disappointed with the behavior of the site-specific Twitter feeds (like this one). They seem to more or less randomly choose questions to tweet and thus a lot of relatively bad content winds up getting shared. (But of course you can make your own judgment about this) – David Z Dec 7 '13 at 22:56

@DavidZ: I get your point. Questions under bounties and Can you answer this? stuff (in twitter) can sometimes be bad. But, others are quite okay (probably highly voted stuff) :D – Waffle's Crazy Peanut Dec 8 '13 at 3:30

The new image is even worse and it does not comply with the size requirements. Think about why you think this is relevant and build on that. If you provide a good mock-up made e.g. in MS Paint, I may have time to make a pretty version. Have a look at the other ads: they all say pretty much right away why you should click on them with the possible exception of the two space.se ads, which are graphically strong enough to stand on their own. – Emilio Pisanty Apr 21 '14 at 11:30
