Don't forget that another great way to get people here (if you don't run any type of high-profile site that may be giving off banner impressions) is to donate (link at the bottom of the page - click the PayPal logo). You can send in however much you want. Tony hasn't put a recommended donation, but I personally would go with $25 - that's enough to buy another classified on Fark, and that seems to be getting some decent people here. So yeah. There's always that too
Don't feel bad if you can't do $25 though - $3 or $10 is just as good
