Fresh idea or not, that is the question?

If Habré is not cross-posted, then you want to ask for advice. The idea came to me here to create a whole series of useful sites, and I put this idea on StartupPoint (because it’s not a pity, and I’m not going to do 100% of all this in the next year and a half). But for some reason, it zaminusili. And now I am perplexed, is it really a “bad idea”? After all, in my opinion, both an attractive niche and a commercialization model are imputed ... I want explanations, not monosyllabic answers and your minuses-pluses.
