Coach Deb and Warren Whitlock put together an outstanding eBook called most appropriateley, The Twitter Handbook. Check it out!
Even if you’ve been using Twitter for any period of time, I suggest you take a look at the information. When I got into the "meat" of how to more effectively use Twitter, I picked up some nuggets of gold.
It’s worth the read.
