One of the great advantages of our new realtime analytics platform is the flexibility it allows us to add new sources and expand our reach and coverage. On that note, we’re happy to announce that as of earlier last night we are now tracking Friendfeed, Reddit, Tumblr and Blip.pl in realtime:
For a complete and updated list of all the engagement sources, take a look at our PostRank page. At the moment, the only two non-realtime sources in our system are Google Trackbacks and Comments – we’re working on improving the speed and frequency of these checks.
Of course, you can also expect more additional sources in the future. This is just the beginning of our vision for PostRank as a discovery engine for the Social Web!
