I've cited the back story regarding my involvement in the summit along with the smart grid space in general many times, and if you don't have that, here's a recent post about it.
I'll be flying to Austin on Monday, and if you're there, I won't be hard to find. As you may know, I've been writing a fair bit to support the summit, and my latest is a Q&A I did with Intel about the role IoT plays in how utilities evolve for 21st century needs.
Once you see that, my other posts won't be hard to find, and I'll continue blogging and tweeting throughout the event.
Oh, and if you're there, I'm hosting the Open Mic event bright and early on Wednesday at 8am!
