I'm not using Twitter until after Easter. I've honestly not missed it as much as I thought I might. I still think of super-cool tweets throughout the day, but I also think of super-cool blog topics throughout the day (not that you'd notice, though, since I have zero time to even shower on some days) so I think my use of Twitter is just another medium for writing.
I like to write. I'd still write even if no one was listening (er, reading.)
That being said, this video is awesome. And, having just twittered through the labor and delivery of my second child I can completely realte to the last scene. =)
