It's his conference he made because he was banned from railsconf.

aha, that explains the podium. Thanks for enlightening me. Kudos to Railsconf.

No kudos earned. They didn't ban him, they just didn't invite him to give a keynote. Then Ruby Central put him back on stage for a RailsConf keynote q&a. It was the snowball that started rolling an ongoing avalanche of secondary crises.
