I sent my first tweet today. Not quite sure what I'll use Twitter for other than to update my Facebook status occasionally (can't change my 'skeleton action figure' profile pic to match the status using it, so only of limited utility).
Nevertheless, it brings me into 21st century media more fully (Skype, Twitter, Facebook, and a blog), so I guess by definition I'm much more 'cool' now. Right?? ;-)
If you're on Twitter, let me know your ID. I'm "primatebonz" and my ID picture is the one to the right.
