Well of course you should be on twitter.
Do you really need to ask?
Because you are in business and you need to be seen and heard in the marketplace. There are currently 175 million twitter users out there waiting to be seen by you.
Why do they want to hear from you?
Because 40% of what's on twitter is "pointless babble" according to the research team Pear Analytics. You would never post "pointless babble" would you?
So it's fairly easy to stand out on twitter. Just don't post babble.
So sign up for twitter and start posting.
If you need any help... you know who to call.
