We just posted a new case-study on using wikis as a People’s Portal at Informative.

Also of interest, is how not just wikis are being used at Disney, but how to introduce the cutting edge to regular business folks and how Socialtext participates in an ecosystem of tools with Moveable Type and Newsgator.

We have also outlined our vision and progress for Wiki 2.0 that stays true to social software principles.

Also, the word at Web 2.0 is Rojo looks pretty damn cool, Snap provides a different kind of open structured search, 37 signals has a great design practice of iteration, and of course, Flickr is all the buzz.
