I made a dating site back in the day. The launch couldn't have gone any better. It went completely viral, got featured all over American TV, I had 4000 users overnight.
And... I made just $40! Why? Dating sounds cool. But it's an incredibly hard market to make any money in. Especially as a bootstrapper.
Let me give you another example. @dantelex (sharp guy) launched a site called Barttar last year. A site where you could trade (or barter) your skills with other people. It sounds cool.
