Karen,
I totally agree unless you are a celebrity like @diablocody or @stephenfry. For them, it's expected to say whatever comes to mind. It's like IM except saved for the world to see.
I agree Ron, this is most definitely for us common folk. Unless you are like me. I generally say whatever I am thinking to peoples faces (or on HSTV,) which is why I don't both tweeting it. :-)
Karen:
I agree. Although, my boss often thinks I'm nuts for following @shawnp0wers and @julietlandau. (But I have a great boss.) :-)
