For a long time, i was contemplating to categorize my posts and apply new themes to my blog. Also, I wanted it to be developed as a single repository for all my posts. In the process, found a few blogs of word-press having those and decided to move to word-press. And, it has paid of really great. Along with the ones mentioned, there are a lot of goodies in Word-Press like file-sharing, links to flickr/twitter and many more.
