I’ve just added a Postrank link in the sidebar for Postkiwi, similar to the link I’ve included on The Inspiration Room Daily.

I first became aware of Postrank when the AdAge Power 150 list of advertising/marketing related blogs started using the site in its ranking. The alarming news at first was that the Postrank site had allocated the feed for The Inspiration Room Daily to its predecessor, Duncan’s TV, meaning that my rank on the list had been dropped from 100 to 300. After a couple of weeks the Postrank team seem to have fixed things up. The good thing is that the AideRSS team behind the site have someone on staff providing a quick response to queries, using Twitter, a blog and bulletin board. I’ve been able to claim both The Inspiration Room Daily and Postkiwi by adding a blank html file to the root directories for each.

Postrank was developed in 2007 by Ilya Grigorik, Francis Lau, and Kevin Thomason to deal with daily information overload and our overflowing feed readers. It’s an RSS feed filtering service that measures “social engagement”, run by Canadian start-up company AideRSS . The Postrank algorithm monitors interaction with blog posts, putting together a score out of 10 for each post from the number of comments, incoming links, internet bookmarks (Digg, Twitter, Stumbleupon etc), clicks, and page views to find popular posts in a feed. PostRank filtering is built into a Google Reader Add-on, a Firefox Add-on and a Web widget, each designed to help users find the most significant posts in the blogosphere, arranged by topic.
