Is it just me or does it seem lots of smart people are starting to publish screencasts?

Eddie Smith did his first at Practically Efficient on Markdown and Notational Velocity.
Yuvi Zalkow did an epic job of Scrivener from his point of view.

I love the way this is all reaching critical mass. Speaking of which, my first episode of the OmniFocus screencast releases this weekend in the Mac Power Users feed.
