Lately I've been making small web sites just because I like the ideas behind them. One, http://www.nobodynotes.com , allows people to browse and leave anonymous notes. The other, http://www.phobiatopia.com, collects and maps people's fears.

They have less practical value than even truemors.com, but it'd be really great if they could generate revenue somehow. Right now, though, I apparently don't have enough imagination to come up with a working business model. I actually consider these sites to be minor works of art, made for the pure enjoyment of it and serving no practical purpose. So is it possible for such a web site to make money? And in particular, would it be possible for one of my sites to make money?

Thanks :)
