SXSWEdu. We're located on the fourth floor fairly close to the Registration Desk. The lounge is being presented by Compass Learning and will have interviews of key presenters at various times each day. For example I'mm listening to an interview with Paul Smith of LearnSprout as I'm writing this post.
In the lounge you can relax, check email and twitter, write a post or just hang out with some cool folks. There's coffee, tea, and water and a decent amount of places to plug in and recharge your devices.
Come on in and say hello.
