The dawn of a new year, 2015, now approaches, or has already approached, either way it means that it is now time to reset our Community Promotion Ads!

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 the mathematically inclined
  • 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.

    $\begingroup$ Trivia note - this post ID is 19014, and the ID of the previous ads thread was 11920. That means that in the span of a bit over a year (rather close to 13 months, really), over 7000 posts have been made to the Mathematics Meta site. That's the highest amount in that time span on the network, towering over Ask Ubuntu's ~4600 sitting in second place. $\endgroup$ – Grace Note Jan 1 '15 at 3:33

    $\begingroup$ I totally agree on the graphic quality. I spliced this thing together last year in Mathematica using the graphic I could find on the internet because Mathematica was all I had. While it conforms to our community ad requirements, it would be nice to see something better that conforms. Thanks for putting it back up, I did not notice until now; terribly busy. Desmos deserves better. Initially, I thought I would email Desmos around Christmas and have them make us something that conforms, but the issue just escaped my time. Any improvements here would be very appreciated by all no doubt. $\endgroup$ – J. W. Perry Mar 29 '15 at 6:29
  • $\begingroup$ I used this graphing calculator and loved it very much. Its been a great help with my ideas. I hope Desmos will someday be as powerful as Python. I hope they make an even better ad next time. $\endgroup$ – Arbuja Aug 27 '15 at 19:41

    $\begingroup$ The light grey text is hard to read and detracts from the message. If I didn't know markdown, "smart" would just look like wasted pixels. I suggest dropping the "*", bringing the grey text up to full black and perhaps softening the grey text with a lighter font weight. The image did catch my eye. $\endgroup$ – msw Jun 28 '15 at 17:11
