Have you ever owned a hosting company? Why or Why not?

I'm curious. I currently do because I love hosting people and giving people the knowledge that I couldn't get elsewhere. Plus I provide a service for free and make people happy with it. It is a win/win everywhere!
Nope and I don't think I would. There are soo many other hosting companies that can do a better job than I can. Plus I don't have the servers or a datacenter to use for it.
