I have heard many feedback that the best platform to start blogging would be Wordpress. It has lots of plugins and easily cashed by Google. Two of my domain blogs are in wordpress platform now and one of them just imported couple of months ago. It used to be in blogger and decided to try the wordpress. I had fun changing my theme as part of learning the whole wordpress. I didn't pay for the theme because it was free. Yes, you read it right. You can find tons of premium wordpress themes for free. You can click here if you are looking for free WordPress Theme. They have the best collection of free wordpress gallery for bloggers and easy to download wordpress templates without login or any hassle.
