WikiSym and WikiMania 2007 both have a call out for papers/participation.
WikiSym will be in Montreal, and WikiMania in Taipei.
There seemed to be a good bit of interest in the Open Guides at WikiSym06 when I presented

all the best
(Open Guide to Milton Keynes - heck I bet you guys didn't think we'd find 650
locations to write about in MK, even if some of them are a bit random :-) )
