Summize's mission is to search & discover the topics and attitudes expressed within online conversations. Our home page currently features realtime conversations on Twitter. Also check out Summize Labs for prototypes that harness conversations within blog.. - Faizar

I've found this site to be extremely useful. It's interesting to see how they've changed their core focus. They were originally a product "reviews" search engine that calculated the general online sentiment regarding products by interpreting the words used to describe them (a simplified version of their original service is available in their labs section). It looks like it was smart move to switch to conversation search since their traffic seems to be growing at a nice pace: http://siteanalytics.compete.com/summize... - grag

It's a great site. Tweetbeep.com is also useful for receiving searches in your email. - David Sim

I use summize on a daily basis... for quick RECENT feedback on specific utilities (etc) that I am considering. For the same search Google often serves up outdated data. - JD 1to1million
