If you want just to comment you don't need to create a Disqus account (this behavior was from day one). You can go to any website that has Disqus enabled and comment with just your OpenID account. However, if you want to install our widget on your own sites or become a moderator you will have to create a Disqus account. Mainly because we need to verify those accounts via email. Hope that helps.
