Now you can get a WordPress.com Account without actually getting a wordpress blog with it.
Reasons for getting a Wordpress.com account:
1. If you wanted to leave comments on blogs that require sign-in
2. If you read a blog that uses our not-yet-released members-only feature
3. If you are a writer on an existing blog, but don’t want a blog of your own
4. If you just want an API key
Your subdomain is blocked, e.g. username.wordpress.com just incase you decide to create a blog later.
