A series of monthly wiki-related chats have begun recently. Wiki Wednesdays have various structures depending on the particular meeting location; some focus on featured speakers, while others have round-robin talks, and some are unstructured. Most events are held on the first Wednesday of each month. This month, events were held in the San Francisco Bay Area, Portland, Oregon, Montreal, Vancouver, and Ann Arbor, Michigan. New events are scheduled for London and Chicago on Wednesday, November 7.
