I attended UnSummit 4 yesterday at CoCo, the coworking and collaborative space in downtown St. Paul’s Lowertown:
UnSummit is an alternative, "unconference," not unlike a BarCamp. That means full participation, full dissemination and free admission — all the things that traditional conferences are not.
The unstated theme was social media/PR oriented, though not exclusively. It was an amazingly well-done conference for being volunteer-run and 100% free (no conference fee; free coffee, donuts, pizza, beer, wine, etc.) due to the generous support of its sponsors.
My favorite session: "Feeding the Blog Beast" by Arik Hanson (center photo above).
