Probably means you're missing some critical usability feature, i.e. you're not solving the whole problem. Few ideas are all bad or all good, and things rarely tip all by themselves. But people don't use a product unless it solves their whole problem without making them hunt for missing pieces - that's really the difference between "project" and "product". If you're missing a piece, it'll never get off the ground.
The missing pieces are usually pretty subtle too - FaceBook took off largely because it was explicitly designed around existing physical social networks, like colleges. Many other people had done similar sites years earlier, but they always focused on building a social network out of thin ether, rather than leveraging offline social contacts.
