The Verge has a great #Fediverse explainer out today: theverge.com/24063290/fedivers

I took the liberty to quote two sentences from the piece and proposed them as a vision statement for what the W3C's Social Web standards activities vision could be going forward. Because @davidpierce's description of the fediverse is a bit more aspirational than what's implemented on the ground today, but it's a good aspiration, doable, and worthwhile. And IMHO what users expect.
