But I literally have EVERY feature he has. It's kind of freaky, but it's a very basic site he's put up. His upcoming features also have a huge overlap with mine. He has, however, gotten lifehacker coverage, as well as on a couple of other sites that drive in traffic. It's a pretty untapped space where even the simplest ideas are a big deal at this point, so I don't want to be charged with ripping him off. Should I delay my release until there's a substantial improvement on his?
