I thought it was interesting that in Will MacAskill's recent posts about decentralising EA, he said that he will avoid giving opening and closing speeches at EAG.
Currently, the process by which speakers are selected for EAG appears opaque to me, and most talks appear to be by 'senior EAs' and 'EA leaders' with high social status in the community.
To tackle the risk of certain individuals being selected based on social status in the community, I think attendees who are accepted should be able to submit blinded applications containing ideas for talks and workshops for EA conferences. The talks and workshops that the conference organisers believe will provide the most value should then be selected.
I think this could be a nice way to achieve greater value from EA conferences, increase the diversity of speakers / workshop hosts and reduce the impression of specific individuals being 'the face' of EA to spread out PR risks and reduce groupthink.
Blinded is a bit tricky: it's often the case that whether a talk would be worth attending depends on who would be giving it.
Another important difference in this case is that the reviewer can evaluate the entire article as it would appear to the audience, while with a conference talk they only have the proposal.
