I may have been radicalized during my short time in the academic world, but IMO, conferences are a really bad setting to disseminate new ideas. They just don't favor it. In practice, you have people preaching their ideas, a lot of people not listening, and a few misunderstanding. Nobody else.
Spreading ideas is better done on paper, with guided discussion, and without time limits. Or, in other worlds, on something like paper-split hierarchical internet forums.
Conferences can be useful to discuss and work over known ideas. For that, they should always bring papers that are already published, and had some community attention. The idea of debuting new ideas over unprepared people is antagonistic to that goal.
