A good example of something technically interesting but which tries to solve a problem nobody really has - Unite tries to dress itself up as “social” and “free”, but, in the end, is a P2P infrastructure with web-based applications on top that requires you to be an Opera user to run them. And momentarily ignoring the fact that this is an alpha feature of a beta browser, how many people do you know that are running Opera on their desktop at all?
