Could we pay for the upkeep here?

In an earlier question, someone mentioned that the founders pay for the server fees here out of the goodness of their hearts, although they have moved onto other projects. I know a lot of us really enjoy this site and consider it to be a special place. What if we made a paypal or something for donations?

Depending on how successful it is, maybe we could pay for other things too. It’s my understanding that the mods delete hundreds of spam questions and work for free. We haven’t had a lot of new members recently, maybe we could pay for advertising or SEO.

Is this feasible? Can you guys fine-tune this idea?
