Puzzling that Twitter has been around for seven years, I have been a fan since 2008, and I still do not have a handy Twitter 101 reference guide. A quick Google search and appeal to my network found many presentation slides, but no handouts related to the art of Twitter. So I made my own. Twitter has great resources, so I was able to edit content and remove links to pull something together. Nothing fancy as of yet, but if you need something in a pinch to introduce a new colleague to Twitter, enjoy!
Useful guide to using Twitter during events from high school journalism teacher, Sarah Nichols.
