I really like the fact that you did not try to create yet another social network and just exploited the existing social graph of twitter to make the connections. I totally agree with thehodge about the fact that a natural extension would be to use also the facebook social graph to offer a beter ux. That said, the site seems a bit too dependent on twitter. I just added an "unlinked person", meaning somebody without twitter account and it seems impossible to add a picture or an url for those persons. The UI is very nice, except maybe for the intrusive tag at the top left. It is too big IMHO Finally, as this is a "startup review", is assume you wish to make money with this. Do you plan to do it with referees fees from Amazon for the sales of book ?
