Indian Government's stand on blogs

A couple of weeks back i was totally surprised and annoyed when I first heard Indian Governments announcement that it will not allow blogging in India. All the blog sites where blocked by the gateways.
I was wondering what would have made Govt. Of India to make such a move. If there were genuine reasons i am happy. I could think of some and I believe so.
But now that I am able to blog again I am very happy. Thanks to Govt. Of India for allowing us to share our thoughts and experiences.
