I was hoping to see much more discussion on this thred, but seems the thread died about a year ago. W.r.t. donations, do you think that could be a monetization biz model? Though, if I like a site, sometimes I buy their premium service, not exactly because I need it, just to support them. Do you think a site can be sustained on donation money like that?
