This really bugs me! This "join twitter" thing on the scroll is not even the worst experiment in user hostility that they have done. Much worse was the time that if you clicked a tweet, it displayed that tweet with the "join twitter" dialog box, and if you dismissed it, it just took you back to the original tweet using history hijacking. That was just bizarre -- how do they expect to sell the idea of twitter to a non-logged-in user if they make one of the most basic actions (navigating to a shared tweet) impossible with deliberate user hostility?
