I always just append the word "Reddit" to any review type searches, it's been tremendously helpful. The peer reviews on Reddit are top notch, give it a go and I bet you'll be pleased.
I'm just amazed by how many people do this. I always do this too since it seems hard to find quality content just by searching on Google. I try to search HN too sometimes like this but the crowd and topics here a lot more narrow.
Reddit has an API, sounds like a cool idea! Roogle - the best of Reddit + Google
