@Christofian We should start compiling ideas of what to write about. Latest news about tools and CMS's, SEO tactics, etc. I personally think we should start with an introduction with some Webmaster's news (Like the Greatest-Hits) and a few other minor subjects.
I think one of the early blog posts should be about the best SEO tactic of all - optimise for humans before worrying about search engines. You can see this theme coming up again and again in the answers to the SEO questions.
