It is possible to add feeds to the chat room. For example, a lot of sites like to add the meta site as a feed so that new meta questions show up on chat. It is also possible to follow a particular tag of another site and get alerts in chat whenever a new question with that tag is posted. It is even possible to add a feed with questions from the main site with a particular tag (e.g., if there is a problem tag that the community wants to watch for abuse).
In my experience too many feeds (or feeds that have too much activity) are annoying, but a few feeds can be helpful.
Are there any feeds that we should ask the mods to add into the main chat room?
