You spend half your leisure time working out how to say things in 140 characters? Then you've caught the tweeting bug and Twitter is for you. You wonder if there's anything else you can do with the blessed creature? Looking for one of those quick-start manuals you get with DVDs and cameras maybe? A spreadsheet with a list of the most common features?
Surely not anything more verbose than that?
Well. You may have thought it entirely impossible, but how about an entire book on the subject of Twitter?
