I'm introducing Twitter today to some colleagues.  Some handy resources (some of which have just come my way yesterday or today):

• Should You Be on Twitter?  (Readhead Writing)  Questions to ask yourself to decide. 
• The Ultimate Guide for Everything Twitter (Webdesigner Depot)  Outstanding place to start. 
• The Twitter Guide Book (Mashable)  Second place to go. 
• Help Resources / Getting Started (Mashable)  Third. 
• Guy Kawasaki 's notes for demonstrating Twitter.  Sorta idiosyncratic. 

And, search this very blog with "twitter," "microblogging."
