you think an online food marketplace is a unique idea? Geo-location services? Unique? Why do you think so often two similar movies are released close to each other (Antz & Bugs Life, Volcano & that crappier one, etc, etc) Better example: When http://nowdothis.com/ http://nowdothis.com/ came out, another 2 or 3 alternatives came out within a week of each other -- you think people "stole" these ideas from each other? I think it's far more likely that people just came up with similar ideas.
