What does your email signature say about you?

InformationWeek.com editor Mitch Wagner did an informal survey of all the messages in his inbox, and drew a few conclusions in his blog about what email message signatures say about the sender. Wagner says:

• Important people don't bother with e-mail signs.
  
• The longer your e-mail signature, the lower down the food chain you are.
  
• Marketing people have company slogans in their e-mail.
  
• Some people's signatures are way too long.

Well I get tempted to agree on all of them. When I was new to my job, I wanted to boast about my company through my signature. But now I am 'matured'. ;)
