I carn't see any redirect of his blog to a google secure page, so either he has fixed it or i am looking in the wrong place?
I'm with vagrant. It must have been there but he was alerted to it and had his web team fix it because I clicked and it went straight to his blog as it should have.
Works fine now. But his new post really nice: http://www.mattcutts.com/blog/seo-audit-video/ Even Google itself is not perfect from SEO point of view.
Why do people take time to create a blog post about an error on another blog? Why not just contact the author of the blog and point out the problem? Strange!
