I'm thinking that Google Plus Communities might be the best way for us to communicate on the ground while at Summit.
I know we setup a Groupme - and that's good for announcement type communication. The problem being that you can't have any type of conversation around a topic and the scrolling of messages can become very fast.
Have a look at this Google Plus community.
We could post photos and have discussions around topics. Plus it's much better suited for anyone wanting to follow the action from their computer/tablet.
