Curiosity consumed me, and Google provided some intriguing results today (2012.09.11):

• "massive open online course" – over 400,000 hits;
• "massive open online conference" – eight (8) hits, all from 2011; 
• "massive open online community" – six (6) hits, all from 2012; and
• "massive multiplayer online games" – over two million hits, for sake of comparison.

Though the middle two searches above for "... conference" and "... community" include a few redundancies, the recency of those few hits may indicate avenues for if not of innovation.
