Search Engine Optimisation Category Updated

I have manually cleaned out the link rot from the SEO/SEM category, thankfully the category was fairly clean, but it is a few pages shorter now due to dead blogs or never updated blogs being removed. A few were moved to more appropriate categories and some were updated as they had moved to new URL’s.

Also done a little change to the doctype, and the html to fix a couple of minor problems but that should not affect users of the site, other than making some foreign blogs easier to read on screen.

Queue is now at 5301 blogs..
