Recently discovered a site based on a unique idea. It's called Cheques Gallery, dubbed as "The gallery of bank notes made by people doing online." Online earners can submit photos of their cheques/checks -- e.g. from AdSense, Chitika, Text Link Ads, Review Me, IntelliTXT, etc. --  for people to see.

I think this particular site will take off, mainly because the site is based on a basic human need: the need to be inspired. More power to Mr. Cheque who owns the site! :)
