Twitter. Another account (I have too many already). To answer the question"What am I doing?" I'm going to go under the premise that nobody cares, or if they did care, there'd be many other places and priorities to contact me through, so I'm not going to
a) create another account
b) worry about who might be missing me
c) worry about who I might be missing
I have one child who's on Twitter, supposedly to follow celebrities. She was disappointed to find out that whoever's Twittering or tweeting for said celebrity, is a fake.
