The heart of the matter is, a website isn't run for free. Sure, there's a lot of sites out there that you can get on for free, but the bottom line that has occured to alot of Dot Com companies is that you can't get something for nothing. Money is required to keep a site going, and bandwidth costs money. Who pays for it usually doesn't concern the person who browses the site, but the fact is still there. I'm not saying that Contour.org is a Dot Com company and I'm not saying Contour.org's sole purpose is to make money...but I know by experience the costs and dynamics of webhosting; I deal with it everyday at work (I work for a national ISP in Pennsylvania).
I'll give whatever it takes to make the site keep going. If it's all for naught, at least I can say I tried instead of just letting it go to save myself a couple of dollars a month.
