Renderosity looks o.k. to me, and it does its job, so I'm not complaining. I see some really bad sites every day. A bad site is loaded with cookies, pop-ups, pop-unders, and bleeding-edge bells-and-whistles that make it incompatible with some browsers, problems that make it display wrong, and problems that make it difficult or impossible to navigate. Renderosity doesn't exhibit any of those symptoms for me. They'll never be able to satisfy everyone's design criteria, so the important consideration is a functional site. Whether it's pretty (or not) will always be secondary to ease of use.
