(Via Attila) The invitations for the 3rd SciFoo have apparently been sent. It will be held from the 8th to the 10th of August at the Googleplex. There is also an idea floating around to organize a BarCamp at the same time as SciFoo. A BarCamp Check out the BioBarCamp wiki and discussion group. There are already several suggestions for venues to organize it and several people interested in attending.
On a side note it's fun to see something like this getting thought of and set up from Twitter/FriendFeed conversations. I have been trying out FriendFeed for a while now and although I am not a big fan of micro blogging (yet?) I really like the conversations around the feed streams.
