Are coming from you, and you, and yes, you!
A voice in my head is what you all are each time you post an update on Facebook, Twitter or wherever. It's what I am to you as you read this.
I trust you enough to let you inside my head and you trust me enough to reciprocate.
Sometimes what you think is trivial seems fascinating to me. Sometimes what you think is fascinating seems trivial to me.
Whether trivial or fascinating these little glimpses into each other's heads are new. We have never experienced them before, certainly not with this scale, immediacy, and intimacy.
It is worth paying close attention while we play with this new found ability.
