While its true I created the FB wlug group, I don't think we should use Facebook... I'd rather we own our data. Plus it would end up excluding too many people.
A broader question we should ask is "what do we want the wlug website to be?"
One thing that I think we should try to do is start recording talks and putting them up on YouTube and then link to them from the website.
I'm all for the wiki, just that we'd want to think about access controls, etc. merely to keep the vandals off. I think this is easy, just force accounts.
