I have 2 of the same Wordpress blogs, one hosted at Wordpress.com and the other hosted under my Hostgator plan (with the Fantastico tool).
I've been focusing my efforts more on driving traffic to the Hostgator one. It seems, though, that the one hosted at Wordpress is getting a lot more traffic naturally.
What is the benefit of using your own hosting plan for a Wordpress blog? It is just a text-based blog with no large files. Should I just focus on the one hosted by Wordpress? Will I get more natural traffic that way because it is a part of the actual Wordpress site?
