The idea: To have an at least annual conference of wiki developers, both for improvements of their respective wiki engines and for standardization. This can be done as part of an existing, large conference at first.
Possible venues:

editThe idea for such an event popped up again during Wikimania 2010. The event will start with an Un-Conference/Open-Space that lead to small groups for discussion and hands-on programming. The name will be shortened to WikiDev. The event will take place right after TikiFestBerlin2010 at the same location.
Date: Sat/Sun, 13/14 XI 2010 Venue: to be discussed (c-base, Lette, ..)
