In my opinion, Twitter is the easiest way for people new to social media to get involved. Here's my list, in no particular order, of the top 10 PR educators to follow on Twitter, inspired by Darren Rowse. I'm sure I'm forgetting some good ones, so feel free to add them to the comments. What I enjoy about following all of these people is that you get to know them and their personal interests, because they tweet about themselves as well as PR education issues, helpful links, etc. You can follow me on Twitter, too.
A number of other educators have recently joined up, so you could also check out Dr. Emily Kinsky, Bill Sledzick, Dr. Meg Lamme, Rosanna Fiske, and Urkovia Andrews, and if you read Spanish there's Fernanda Grimaldi.
