AideRSS Opens Up PostRank


ScreenshotWe’ve covered the RSS ranking service AideRSS a couple of times before – in a nutshell, they analyze the activity surrounding an RSS feed to help you identify the most talked-about items, on the theory that those are the ones you should pay attention to first if you’ve got limited time. They’ve gotten some traction through their integration with services like NewsGator and Trawlr.

Now the AideRSS folks have taken another major step: they’ve opened up their core PostRank technology for anyone to use. As part of this effort they offer more details on PostRank than before. You still can’t see the exact formula behind the calculation, but they explain the forms of engagement they watch for: creating, critiquing, chatting, collecting, and clicking.

If you want to see PostRank in action, you can visit the AideRSS site – but even easier for many web workers, you can install their Google Reader integration. Available as either a Firefox extension or a Greasemonkey script, the integration allows you to see the comparative PostRank for pretty much anything in Google Reader, and filter things down so you’re only seeing the most-important stories. The new version of the extension works on folders or all items view, a welcome addition to feed-only PostRank.

And that gets us back to the API. In the just-launched API, you can calculate “Thematic PostRank” – the rankings of any set of URLs, not just the items from a single feed. This should make for much more interesting mashups, since it means developers can apply PostRank to anything. In particular, I’m wondering about the possibilities of combining the Thematic PostRank API with Yahoo’s recently-announced BOSS search API. Between the two, it should be possible to find useful information on the web faster than ever – which, after all, is part of what we web workers do.

Blake, you can display your top posts, along with their PostRanks by installing one of our javascript widgets. To get it, head to, type in your blog URL and then click on the ‘widgets’ tab to preview.


Cool…is there a way for me to use Post Rank on my blog? It would be cool if people looking at my blog archives or recent posts could see the post rank on the page itself, not just in my feed.

Jason, we recommend Greasemonkey if you have it. The XPI is essentially a compiled version of the Greasemonkey script and that process is not yet fully bug free – albeit the GM community is definitely making great headway. Having said that, both should work equally well in our case.

Yes, the issues they had with Greasemonkey are resolved, provided you use latest builds. I didn’t do any comparative speed testing; they recommend the Greasemonkey script and it doesn’t seem to be slowing down Greader for me particularly.

Do you know if the issue with Greasemonkey is resolved? Which is more reliable? GM or FF? Which is Faster? ~ thanks
