If you're interested in design patterns for rich interactions or web 2.0 design patterns in general, and you can get yourself to Switzerland this summer, then you might want to submit a proposal for the pattern-mining workshop at TOOLS 2008 Europe that Dragos Manolescu from Microsoft Live Labs and Joe Yoder from The Refactory are organizing.

It's currently scheduled for July 5-6 (but the dates are still to be confirmed), and the organizers are looking for systems experts, domain experts, and experienced pattern writers to come together and identify best practices in existing web 2.0 applications and services.

Here's a description of the workshop from the call for proposals:

Web 2.0 features are now commonplace — blogs, wikis, RSS feeds, social bookmarking and the like are almost everywhere you look online. Now that these technologies are maturing, what are their common problems and challenges? How are these problems being solved? What similar challenges do Web 2.0 developers face, and how can they leverage the most common solutions? Here’s your chance to gather with other professionals facing the same issues and work together to identify solutions.

Disclosure: I am on the program committee and will help review the proposals. See the CFP for more details.
