mn has plenty of history (you may have heard of youtube, or unisys, or cray), and a good number of entrepreneurs. just no angels. angels can go to hell imho. i'll bootstrap thanks.
Youtube really doesn't count (see johns's comment). Unisys comes from the merger of Sperry and Burroughs which both had their origins in Philadelphia[1] and is now headquartered in PA. Cray started as a MN company, but after a long and colorful history (some would say tragic) it is now headquartered in Seattle, WA.
Well, angels and VCs are needed by a lot of people and MN doesn't have the environment to support a startup community.
