I (like everyone else) dislike logins, but accusing the people who require users to login to use their content of being greedy is simply asinine. Expecting to be compensated for your content and your work isn't greed, and its a hell of a moral power play to label it as such.

That said, I think the OpenID project is going to be/is a fantastic way to eliminate login barriers while still providing most of the benefits of user accounts. It still needs to be pushed a bit more... I'm all for each child being given an OpenID account along with their social security number ;)
