Hi, I think the site looks good, and is very informative. The only question I have, is have you tried moving the 'o' on the logo up to line it with the rest?
Seeing as you post regularly I can see your dedication to the topic, perhaps you could condense the number of posts and rather focus on a smaller number of poists that went more in-depth into topics? For example an in-depth look into Google Penguin would go down well!
