Wordpress.com, the free blog hosting site based off Wordpress, is getting ready to allow users to use their own domain names in conjunction with the wordpress.com service. What’s that mean? You will be able to setup a domain to point to your wordpress.com blog.
For example, I blog at http://slackware.wordpress.com. If I bought the slackwareblog.com domain, I could point it to slackware.wordpress.com. So, slackwareblog.com would essentially be running on top of Wordpress.com. It’s a lot like gmail for your domain.
Right now, Wordpress.com is only testing this feature out, offering it to the first 8 people to comment on the Wordpress.com blog post discussing the new feature. I’ve been wishing for this feature since I started using wordpress.com, glad it’s finally on the horizon.
On a related note, “92.63% of the traffic to WordPress.com is for blogs outside of the top 25.” I figured it’d be lower than that, but that’s pretty impressive for those outside the top 25.

I am not very sure what the domain mapping is in real although I read the article and a friend of mine explained me the basics of domain mapping too.Maybe I need some time to get the things.
