Well, it's a bit late to ask that question. The train has left the station.
Question is, what do Linux users need or want with a user group?
The most famous computer user groups in history are probably the Homebrew Computer Club and the Boston Computer Society, both lost in the mist of time. Their big thing was meetings. Lots of important products made their debut at BCS meetings, most notably Lotus 1-2-3. (People of a certain age will remember that one.) The "Steves," Jobs and Wozniak, were members of the Homebrew club as teens. The founder of the BCS, Jonathan Rotenberg, was 13 at the time.
But what would a 21st century user group do? What would its organizational structure look like? What services would it provide? What services should it provide?
Linux has always moved mainly from the bottom-up, dependent for its success on the kindness of strangers. What will it change if we can make those strangers into friends? What would they ask for?
Lots of question marks here. Got any answers?
