Funding it wasn't a problem. It took a weekend to build and was dirt-cheap to host. If people started using it enough to increase the server costs I would've stuck an ad at the bottom.
Honestly half of why I took it down is nobody was really using it. I didn't work terribly hard to market it, as I had no aspirations of getting rich and it would've been tenuous to monetize at all. I just told friends about it, etc.
I didn't imply there was a "hard part" to it. Just a neat idea. No need to dump on it.
