Happy Birthday Twitter

How long have you been on @twitter?  Did you know that @twitter is 5 years old today.  I'm not exactly sure when I started tweeting(@loricrofford) or what was my first  tweet tweeted, but I do know I have an account (@loricrofford) and so does Mix (@mix941kmxj).  So what was the very first tweet on @twitter?

The first tweet went out March 21, 2006, from co-founder Jack Dorsey - a simple message that read "inviting coworkers."

via Nearly 1 billion tweets per week - Twitter marking 5th anniversary - SFGate.

So do you tweet?  Is @twitter something you use on a daily basis.  Do you find it easy to put a thought into 140 characters?
