You make an excellent point. Right now we get enough traffic without advertising to pay for the server, which is good. IMHO this site will never be a big money maker but we do have the chance to establish a presence as an authority of sorts. Carpet bombing can only damage that.
If history is any indicator, this site will continue to grow on it's own. Last month we had 41,000 hits. As of April 12th at around noon we already had 33,000 hits this month. In other words, the site is growing, and it's doing it quickly.
If I would have know this I would have switched to a new server months ago
Anyway, I like how this site is too, and I hope that the visitors do as well.
