In the not too distant future...
The PLACE of edtech conferences is replaced by the SPACE of edtech conferences.
For attendees, no more gathering in central locations, paying registration fees, paying for plane tickets and hotel rooms.
That model is outdated, slow, expensive, wasteful, and unnecessary.
Space replaces place.
We meet in a space online. Virtually. A Skypecast broadcast live. Possible? Sure. Other ways? Of course. We need to let go of our antiquated notions of how ideas are shared, of how we "teach" others, of how we spread the word.
The technologies we are all so excited about are there for us to use - not just in our classrooms, but in the way we teach each other.
