I suppose I should point out that most people probably aren't aware they can easily change the feed.

It may not be immediately beneficial to a person's WordPress to see Matt's personal blog posts, and just feeding a WordPress News category would certainly correct that. However, I maintain that WordPress is unique. With a million WordPress site owners, every one of them can feel involved. You use MySQL, PHP, and Apache on more projects than WordPress, but can the average user name any of their developers, much less their creators?

Aside from the fact that Matt can do whatever he wants, one thing that initially drew me into WordPress was the community. Drupal, CentOS, Joomla, MySQL, etc could only dream of having a community like WordPress has. At the head of that community is a creator that is very reachable and involved. He isn't some distant executive whom nobody has ever heard of. As soon as a new WordPress user logs in for the first time, they are able to see this significant distinction that WordPress has from any other large scale application they've ever used.
