My girlfriend has set up a blog/website for herself on wordpress.com but also has a domain name she'd like to use when giving out her website URL, instead of a wordpress.com subdomain.
Wordpress has some info about that here:

I'm interesting in knowing more about the pros and cons of handing over a domain to Wordpress like this. Has anyone done it?
