Infospace Pagerank zero

[JoeyJoeJoe]

I notice that the front page of infospace.com is now showing PR0. I wonder what they have done to annoy Google?

Sure its not just your toolbar? I show a PR7

Whoops. On further inspection, www.infospace.com is showing PR0, but infospace.com is showing PR7.

Also, there isn't a cached page for the 'www' version, but there is for the other. I thought that Google was clever enough to realise that the two addresses are the same?

*Sigh* They aren't the same. They're two different URIs with the same content. PageRank goes to the URI, not the content.

I could name a couple of sites where that isn't the case at all. For example, one site that I am associated with has the same Pagerank for the 'www.example.co.uk', 'example.co.uk', 'www.example.com' and 'example.com'. They all point to the same site. Only one of these is actually used anywhere and has any backlinks. So it isn't purely URIs.

I am not sure why Google does this for some domains and not others. Perhaps it is something to do with their server setup, or IP addresses, or maybe even nameservers?
