Wednesday, December 6th is Wiki Hackathon day, at the home office of my employer, Socialtext.
Join us from remote or in our offices in Palo Alto to hack your Wiki project to your heart's content. We'll showcase all projects on this site and elsewhere, provide beer and pizza, and might even have some nifty giveaways for the day's coolest hacks. Virtual participants can join us in IRC channel #socialtext on irc.freenode.net. Visit the wikithon workspace at http://www.socialtext.net/wikithon.
