Heh, personally I like the slick graphics design and the minimalist style. Google is minimal also of course, but something about the large white space makes it seem 'sparse' rather than stylistic. This black/grey/blue thing suits me just fine... although I do share the 'iWhat?' sentiments. Yes, we get it, the search engine is customisable and central to us, our experience, the all-powerful I.
I'm not surprised it's gone down; to be honest I don't know of many web-based projects with lots of hype/interest that haven't struggled with opening-day demand and bandwidth. Cuil certainly aren't the first company or site to fall foul to the practicalities of the Internet .
