I think it would be nice to have an Announcements feature on the SE sites. An announcement would work different then a question in the form that some relevant information to the community as a whole is pushed rather then asked for. Before an announcement goes into the general announcements pool, it would need to be peer reviewed. Then it will be visible to the rest of the community and voted on. I imagine this working similar to a hybrid of the review system for users retaining a certain rep and the definition to commit system on area51. A feature like this would be very valuable. For example, recently I found a great free online course this summer for people interested in Machine Learning. An announcement like this would be applicable to a community like Cross Validated but I was unable to push this announcement to the community because there were no particular questions pertaining to the subject at the time or if there was, the questions were long forgotten.
I think the right way to do this is through a community promotion ad:
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:
- cool site-related open source apps
- the site's twitter account
- scripts packs or power tools
- cool events or conferences
- anything else your community would genuinely be interested in
The last one seems to fit your purpose. If the ad gets enough votes (6, currently) it will show up periodically in the right panel
I think a community ad, as suggested by Micheal, is the best solution, but the site's blog (if you have one) is another viable venue for this sort of thing.
The benefit of using the blog is that since it isn't a Q/A, you don't have to wait for somebody to ask a relevant question. It is also automatically announced to the whole site when there is a new blog post, via a red
new link in the site's header.
