Congratulations to our own Ross Mayfield for the launch of the 1.0 version of Socialtext Workspace, and the simultaneous release of their open source wiki product, Socialtext Kwikspace. (Kwikspace is built on Brian Ingerson's Kwiki, the perl wiki module. Brian now works at Socialtext, so their commercial and open source products couldn't be in better hands.) It's worth a look for anyone tracking the merging of collaborative patterns -- Socialtext has been thinking hard about what's good about wikis and what's bad (as Ross says in his launch post "As a wiki, it's dangerously close to being, well, pretty."), and about how to integrate other technological patterns (post into the system via email, publish out of the system to a weblog) and how to customize it for particular social patterns (controlled membership, event-focused use). Congratulations to everyone at Socialtext for the 1.0. Now get some sleep.
