Themes and SEO

I am a fan of using these themes, and even re subscribed to take advantage of the new blogsmu theme etc. I am a little disappointed in the build of these themes, and find myself constantly having to hack theme up to make more seo friendly, h1 and h2 tags aren’t consistent, and used wrongly, lots of small things that all add up in seo. w3c errors all the time, for a premium theme, i would expect these areas to be thought of, like those in thesis, which validate, and seo friendly. just a rant
