The comments to linked article at coolbloggingtips blog (which uses a free WP theme template design) would be applicable in general for either free version of WP wordpress.com or paid version which is wordpress.org.

Alot of the commments were talking about the free wP theme templates. There are now over 85+ theme templates to choose in free wordpress.com for setting up a blog.

For the author of each comment, you can click on their name/pseudonym which will reveal the commenter's wordpress blog.

The person/owner of the blog is actually one of the wp support forums folks. So she genuinely knows wp free template technical issues/features.
