Wonderful work. How do you plan to sustain the site when it gets too big to fund privately. Is this a for-profit venture?
Ideally, we'll eventually be in a position to run ads internally instead of relying on adsense, and then we can hopefully make a little better money off of that. We also get a surprising number of donations [1] that help keep us going.
By the way, does anyone know anything about marketing? That's one thing we aren't good at. We've gotten very little press coverage. We tell people "if you like it, tell your friends" and that's gotten us this far.
