Here's a USA today article:

http://tinyurl.com/whyNOTtoTwitter

I'm pretty sure I 100% agree here.

I provide training and new software.

I'm not Comcast: I don't care to see what people are saying about me. So I don't read Twitter.

I'm not Dell: I don't offer "specials" usually. So I don't WRITE twitter.

I can't see why I should twitter.. ever.

Someone.. enlighten me.

If it would help to know more about my businesses before you answer, the two URLs are:

Looking forward to your take / advice.
