hehe... yes, I am one of the twittery folks... #busted
Can't stand facebook, LOATHE it, but twitter seemed to make sense to me. Originally, I joined so that I could connect up with someone I hadn't seen for years and years (and to stalk someone else

)
I even have FAMOUS people following me

EDIT: I don't own a "device" though, smart or otherwise - so I'm entirely desktop or laptop bound
