Twitter says "Don't Tweet About It"

I think twitter is using reverse Jedi on me. I have been reading about the new "lists" feature that twitter been working on. Presumably it is the functionality that many have been already using in web applications like tweetdeck and seesmic.
So I was surprised to see this splash banner come up on an account I help facilitate.
I will run to try out the feature now. I just thought it was funny how twitter announced this private rollout.



If you can't read it in the picture, the text says, "Lists are timelines you build yourself, consisting of friends, family, co-workers, sports teams, you name it. You're part of a small group receiving this feature, so don't tweet about it yet!"

They so want me to tweet about it, right?
