I was prompted to articulate this conclusion having read Nipplecharms post. I find it very odd, that given all the effort I put into optimising my main site, and the main sites of my clients, that some of the least optimised parts of my web portfolio are largely unaffected by the depredations of Jagger. Namely, a couple of blogs that I run.
These blogs appear to have weathered the Jagger storm remarkably well. In fact their vastly better performing than the main site. The blogs appear in a number of valuable top 10 positions - but they are certainly not optimised. I barely give a moments thought to the content that's entered.

Any thoughts on why these blogs should be faring so well?
