When I started this blog back in December I advertised it as www.codeclimber.net.nz, but given the fact that Subtext always strips the www out of the domain name when building internal urls, my blog was being indexed by Google with two different domain names:
www.codeclimber.net.nz since it was the url I was giving around, that was linked from my post signatures and so on
codeclimber.net.nz, the url that was generated by Subtext for some of the internal links, and from the rss feed and the Google sitemap
So, to avoid shattering the PageRank...
