First, I wanted to thank all of the Effective Altruism Global organizers and participants. I found it to be very valuable and overall well put together. There was obviously a ton of work put into it, most by conference organizers who I don't believe will get that much credit for it, and I very much commend their work.
That said, there's always a lot of room for new ideas, and I find I often get a bunch of ideas at and after these conferences. Because of the EAGx events, ideas described now may be able to be put into action somewhat soon and experimented with.
As may be expected, I recommend that people make all of their ideas be independent comments, then upvote the ideas that they think would be the most useful.
Split at least one day of the conference into streams:
People who are lobbying on policy have a lot in common whether they are working in animal rights or xrisk so this could bring separate strands of the movement together. This would also help bring together startup founders and successful businesspeople who want to run their companies more effectively (and otherwise might not meet each other because they're obscured by heaps of students). The charity segment would discuss public outreach, fundraising, and some impact evaluation.
Everyone would spend more time with the people who can help them do better at their jobs, and there's more likelihood of collaboration. It seems like a big win.
I agree with the principle of splitting things by type of work rather than by cause.
