In reply to Michael.

Indeed, the confusion between WordPress.org and WordPress.com will be muddied even more. But as a user, being able to upgrade from a free, basic, WordPress.com account to something that allows me to use any plugin or theme I want without having to move anywhere is an incredible convenience.

It does make me sad somewhat to realize how many people will potentially see WordPress.com as THE WordPress, even though it happens already, it will probably increase.
