All the edtech cool kids are gathering online this week at the 2012 Learning 2.0 Conference. Organized in conjunction with Connected Educators Month, the schedule is packed with sessions ranging from hardcore how to’s to big picture vision things. Some of our favorite TL contributors are keynoting including David Warlick, Yong Zhou, and Joyce Valenza. Follow the action on Twitter using the tag #learning20 through 8/25. I am personally looking forward to Angela Meir’s Friday morning keynote. Check it out.
