Mom, This Is How Twitter Works is an excellent explanation with visuals and text of how Twitter works. The post, written by Jessica Hische, explains everything you need to know about Twitter. Want to know what a reTweet is? That's covered. Do you want to know which things on your timeline can or can't be seen by others? That's explained. And just how does Twitter compare to Facebook? Jessica has that covered too.

If you have ever tried Twitter, but just didn't "get it" Mom, This Is How Twitter Works is for you. If you're trying to get your colleagues to try Twitter to build their own personal learning networks online, Mom, This Is How Twitter Works could be a good primer to have them read and or reference.
Thanks to Steven Anderson for sharing this resource last week on Twitter, of course.
