MinneBar -– one of the largest BarCamps in the world – is being held this Saturday at the University of Minnesota’s Coffman Union.

For those unfamiliar, BarCamp is an ad-hoc “unconference” — a user-generated conference that’s rich with participatory workshops, discussions, demos and more. Lots of discussion about start-ups, programming, open source and social media in talks mostly run by average people who are passionate about learning, sharing and collaborating.

This year’s schedule of events runs 8:30 a.m.-8:30 p.m.

Here are just a few panel highlights: Blogging for Benjamins; This Thing called Twitter; Social Search in the Corporate Enviroment; The Mathematical Foundations of Music; Why Should I Care About Grails? Full list here.

More than 400 people have registered already. Everyone is welcome, and the event is free. More info here.
