Twitter users like its spontaneity. You can blog from your mobile phone with Twitter. You can send out an e-blast in the moment.
But if you're a professional using Twitter, remember that your clients are probably reading your posts.
James Andrews, a VP at a public relations agency, was in Memphis, Tennessee, to give a presentation to FedEx. While in town, he had an unpleasant encounter with a local, and tweeted this:
Some FedEx employees read this, forwarded it to their bosses, and soon the higher ups at FedEx who have spent millions of dollars on this PR agency, sent an open letter to Mr. Andrews (not sure if it was meant to be an open letter, but it's on the Web now) questioning whether they want to do business with his agency if he's going to hold their city in such contempt.
Now, it's easy to take things out of context when Twitter posts are limited to 140 characters.
And there could have been more dialogue to sort this out before it public.
But it turns out Mr. Andrews was in town to talk to FedEx about how it could use social media to further its business.

Andrews apologized on his blog, so it looks like he didn't lose the FedEx account... but this still makes for an interesting, modern day cautionary tale.
If you use twitter, feel free to be honest, but assume your clients are reading. And think about how someone with no context will read your posts.
