These two events orbit each other, and represent two opposing styles of a conference. Devcon is the large, centralized, top-down EF-orchestrated event, and Devconnect is the bottom-up, emergent, festival of the Ethereum community.  For those who have been tracking the Ethereum conference world, this is a mic drop moment. A large, official Ethereum event in Buenos Aires has always been on the horizon. We all knew it would eventually come, and now it's finally here.
