I just got a Tweet on Twitter from a @shermanhu who was Retweeting @markshaw tweet which suggested that this post by Gary Kawasaki was a excellent primer on Twitter for those of you who may not have heard about it. I can’t imagine there are many of you but here it is. How-To-Use-Twitter-As-A-Twool. It was represented into a visual blog post by the good folks at Viz-Edu . Sandeep Arora @SandeepVizEdu has done a good job at answering for those of us who are visual learners.
