Not sure if anyone has been monitoring this, but they post new stuff each day as was announced. Some VERY exciting features coming down the pipe:
I think the infraction system can become useful, although I could also see a scenario where it could be abused.
TON of features/additions that give you flexibility over certain usergroups instead of global changes - very nice!
Pop Up List for Attachments - might be a bit easier to moderate, probably would want to see that in action before deciding how tasty it is.
I like the description field in Tasks - makes it much easier to manage!
RSS Poster Bot - probably my favorite new feature of all. I tried doing it once for a quick few minutes and the hax0r is a pain to complete. I can see this giving us the flexibility to doing some creative things to boost traffic
Rep without AJAX - also nice, as I don't like to have to leave the page to do it
