http://www.improvely.com, http://www.w3counter.com, and two dozen other sites over the years. Revenue in the millions over the past 8 years I've been self-employed, and I'm not taking a pay cut versus what I'd earn in industry if I had gone that route instead.

I've run into many limitations that have prevented me from offering products, service plans and sales strategies that would've been profitable but required more employees. I could hire, but I enjoy what I do, and switching from what I do to hiring and managing sales/support/ops teams is a totally different job I wouldn't enjoy so much.
