Well for one, the topics covered on here are far broader than just startups. And for two, a lot of the ones that are startups are actually interesting, they're trying to solve actual problems. In fact, putting aside the incompetence, this one I would say falls into that category.
That said, not all ideas are created equal, and IMO at least, this one is not, and what makes it fall short is so obvious that I have trouble treating it as a serious proposition on the part of the people behind it, let alone one worth putting money into.
