Got back today from attending Barcamp 6 in Milwaukee. Basically it was a 36 hour (straight through the night) of talks/hacking/demoing/learning. The conference is set up to not be a bunch of big wig speakers, but passionate attendees that share their knowledge to the group. I was kinda of unsure how well this would work, but I have to say now, that I AM A FAN!
First off we sent a microphone around the room of 100+ people with the purpose of getting a name and what that person wanted to teach and what they wanted to learn. So that right there changed what was being presented that day, as someone wanting to learn X, inspire someone else to teach X as we went around the room.
Needless to say we need to send more people to this barcamp. The Milwaukee barcamp is very hackerspace focused, and the ideas presented were fresh and fun. I am planning to go back next year.
