Show HN: review my site Cohaico

Today we launched the beta of Cohaico: http://cohai.co

Cohaico collects from Twitter what people are saying about specific things (currently consumer electronics and movies, more verticals coming up).

We are showing the most interesting tweets for each subject and if you sign in - we show you tweets by your friends first. We analyze sentiment and also show what are the most mentioned products. Please take a look and let us know what you think: http://cohai.co
