Interesting approach, dburdon.
I use blogger, too - but use it to post directly to my site
www.maniactive.com/states/blogger.html instead of to blogspot.
In your opinion, is hosting your blog offsite more beneficial traffic-wise to your main site? Because it strikes me that having a content-rich, frequently updated site with clean navigation is beneficial to search engine positioning...
Or is it "six of one / half dozen of the other?"
