Once Twitter posted details of the API in this public forum, that opened the door to our discussing lists publicly (if it wasn’t open already). And I’ve been doing so. I even made a video showing TalkingPuffin all of Robert Scoble’s lists at once on a big screen: http://twitter.com/dcbriccetti/scala
Simply enabling the Lists feature for many users and putting a little message on the Web page saying, “please don’t blog about it” is not a good approach. I’m not complaining, just explaining why I feel fine about talking about it. If I enter into an agreement with someone, I honor it, of course.
