Yup. But it has too strong an emphasis on shopping, listing prices, etc, and lacks a clean hierarchy. Too many duplicates, and not enough reviews, e.g. http://www.epinions.com/search/?submitted_form=searchbar&...

I'd love something with a Yelp-esque interface that allows me to search for any product, whether grocery item or gadget, or whatever. e.g. "I wonder what people think of the Blueberry Stonybrook yoghurt?".

Previously it wouldn't be that compelling, but with mobile computing being what it is now, it could be very helpful.
