Over at RWW, Marshall Kirkpatrick takes a look at whether RSS service PostRank has what it takes to mount a challenge to our dependency on oil Feedburner.
PostRank is one of our very favorite services on the web today. Give it any RSS feed and the service will give you a filtered feed of just the most commented on, linked to, saved and Dugg posts from that feed. It’s really handy, so we’re excited to see what the company can do moving more seriously into the feed publishing and analytics market. Can PostRank pull it off?
Can PostRank pull it off? I’ll let you read Kirkpatrick’s analysis but I’m not putting my money on PostRank.
While the concept is great–forget the number of items in your RSS feed, which ones are the most valuable–PostRank hasn’t evolved much in the 2 years I’ve been aware of it. In fact, as it’s grown in popularity, I wonder if it’s starting to groan under the strain of trying to process so much data from each feed. Take a look at these two basic errors that render the tool practically useless:
Can someone explain to me how an item with just 4 comments can have a higher PostRank than one with 5 comments and a bunch of other social media bookmarks?
Or this anomaly:
The sidebar widget gives “A Comic Reminder to Avoid a Social Media Reputation Blunder” a PostRank of 7.4 yet the main search results say it’s only a 6.5.
Don’t get me wrong, I love the idea of PostRank and, with some additional funding, it may be able to provide more consistent results, but consider this. If Google–with all of its billions–can’t get Feedburner to accurately display the number of feed subscribers each day, we’re probably a long way from being able to accurately measure anything more complex.
Still, PostRank wants your ideas for improvement. Leave a comment below or head over to their site and share your thoughts.
