A while back there was a poll on the BuddyPress website about what should be tackled next. BuddyPress is a plugin for WordPress MU that turns your install into something of a social network. It is currently out in 1.0.1.
The results are in and among the things we’ll see in BuddyPress 1.1, apparently due August 17, are filtering of the activity stream, group categories and tags, image posting to wire as well as quick posting to blogs through the theme, and some other things. Not counting bug fixes an other things that might arise along the way of course.
