Many beta-sites suffer with a problem of voting. Code Review is one of them. We at Code Review have realized that it is hard to vote for answers that you're not aware of, therefore some of us (no monkeys named) posts a link to a recent answer every now and then in the chat.
Instead of us posting answer links in our chat room manually, which sometimes can give us an uneasy feeling of possible rep-whoring, we would like to add a RSS feed to the chat room to let the Stack Exchange bot announce all the new answers for us.
I understand that big sites such as Stack Overflow won't be needing this as there would simply be too much, but I believe that there are many beta sites in which this would encourage more voting which would lead the site one step closer to graduation. (Give us six to eight weeks of using this feature and I can come back with some data from the Data Explorer, which we're very happy about now that it includes beta sites)
Please add an official feed with a link such as http://codereview.stackexchange.com/feeds/answers which can be added as a Chat Room feed.
Edit: I also think that answers for questions with a specific tag could be useful for chat-rooms. With a feed link like http://codereview.stackexchange.com/feeds/answers/java
Edit2: Not only would it be good to filter by tag, it would also be good to see new answers for the meta site, which also could use a feed. Not everyone visit the meta site every day, or as often as the main site, so feeding answers from there to a chat room will most likely increase meta activity and awareness. I'm hoping to see http://meta.codereview.stackexchange.com/feeds/answers in the near future.
