RockMelt

RockMelt adds your online contacts right into your browser. It does away with the concept of going to a social network to do your social things, and instead makes ‘social’ into an ubiquitous experience across the web.

Does that sound too complex? Just to go to their website, watch the video, and everything will make sense.

Please note signing up for the beta is done via Facebook Connect instead of the regular mailing list.
