Twitterwatch: Another Big Week For Twitter?

Try just an incredibly big 24 hours...

While last weekend saw Twitter fighting of a bit of a worm, this week ends with the early bird getting two pop culture milestones that can't be ignored.

On one hand, the first Twitterer reached one million followers (and the second, Ashton Kutcher's announced competition CNN, appears right behind him to do it again).

But today?  Oprah joined Twitter.  And in all caps, no less.

You have been warned. :)
