Tracking the social graph: Plaxo launches Pulse
Plaxo is one of the best address book syncs we've come across. Now they've launched a new feature which lets people sync their social profiles. It's called Pulse and and it allows you to aggregate your data streams from social sites around the web. Not only that. You'll also be able to subscribe to your friends feeds.
There's an increasing trend of social applications that provide all-in-one locations for tracking your “Social Graph,” as pointed out by Dino on Chroma Inc. He defines social graph as “the aggregate sum of our network and connection, the bits and pieces of information and content we pull together in various applications (Twitter, Flickr, Last.fm, Facebook, YouTube, Pownce, the list goes on).”
