I haven't really got into FriendFeed just yet but one of the useful things about it is the concept of the room. A group of bloggers who went to the ISMB conference in Toronto created one such room into which they could tip a bunch of micro-blogs that covered the key points of the keynote.
According to a comment from one of the bloggers on Nature's Seven Stones blog, there is talk of pulling microblogs into next year's conference.
