Hmmm… Here’s a site that claims to be able to estimate the Google PageRank of any web-page. Memex comes out at 6/10. Statusq gets 5/10. BBC Online gets 9/10 — higher than Amazon.co.uk (8/10) but dead-level with cnn.com (9/10) and BoingBoing.net (9/10). Google.com, needless to say, has a PageRank of 10/10.

I’m not sure I believe these results, because I can’t see how they’re calculated. And since the site is independent of Google and the details of the PageRank algorithm (as distinct from the general principles embodied in it) are secret, it’s difficult to see how one could check the computation.
