Here are two of my favorites:
Shelly S Terrell - @ShellTerrell
Among the very top educators on Twitter, Shelly tweets a consistent stream of fantastic new resources for bringing technology into the classroom. An expert on webinars and global education collaboration, following her is one of the most direct routes you can take to get connected with other like-minded educators around the world. She’s also part of the brilliant tweeting team @TheConsultantsE which is worth a follow for great teacher tech training advice.
Steven W. Anderson - @web20classroom
As the co-creator of the phenomenally successful #edchat concept, Steven has firmly staked his place amongst the glitterati of e-learning experts on Twitter (should that be the Twitterati?!) An education speaker and blogger and an award-winning tweeter, Steven is constantly at the frontline of education technology advances, so following him is a sure-fire way to ensure you will receive all the very latest news and updates while they’re still red hot.
