As you probably know virtualization.info relies on Google Blogger engine. Blogger is great and becoming better and better every day but has a missing killer feature: post categories. I know even with search feature it's very difficult to find articles about a certain topic so I implemented a new Tag Cloud feature: simply take a look at it and discover top 20 keywords on virtualization.info, linked to as many articles as possible about that subject. I hope this can improve your experience (at least till Google won't provide post categories or native tagging). Enjoy your stay!
