I had a great time at Eclipse DemoCamp Vancouver 2009. There were some really interesting talks, and the pace was good with 9 minutes per presentation. In particular I was really impressed by a presentation by Emerson Murphy-Hill titled Identifying Code Smells in Eclipse. Emerson demo'd a tool which augments the Java source editor with ambient code smell decorations. Neat stuff.
Anyone that is interested can find my slides on Crowdsourcing Documentation here. In a nutshell I presented on how Mylyn WikiText can enable the use of a wiki (such as EclipsePedia) for creating and maintaining documentation while still publishing to other formats, such as the Eclipse help system. This idea is evolving within discussions by the Eclipse Architecture Council on bug 283734: Documentation Best Practices.
