It sounds like a wonderful project, and the page design is quite OK. Hmm, everything looks fine.
But how about of its usage actually? It indexed many sites but they are not good connected. Sometimes you searched a website what is not well-known, in the similar sites list you will probably find not even one site is actually similar to that, all results are useless!
Users can contribute it to optimize their database. I tried that, I thumb up'ed one website and re-check it one month later, nothing changed! WTF? I don't know how many thumb ups are needed but very few people just did that so I thought I could be a important power but no.
I suggest don't waste time on it.
