I am looking for a blog that has a lot of updated content on SEO news etc. I.E googles latest thoughts on "xxxxx" or bing's recent advertising campaign. I am looking for a blog like this generally so that I can just get some compact news but also for a site where I can tweet relevant posts that I find interesting and useful. However, I would prefer if the blog isn't just a sub page on some SEO Company site. Most of the ones that I have come across are just blogs that aren't actually dedicated blogs! Can anyone point me in the direction of a few?
