I thought it was too hard to start a company with a single founder because Paul Graham said so. That guy knows everything about start ups. He is possibly the greatest entrepreneur of all time and didn't benefit from a bubble or anything. Anybody more successful than pg only got there due to luck. Everybody involved with start ups should just read everything he writes, conform to it, and help spread the word. You can't become a trailblazer until you embrace this dogma.
