Good point. Given that Eliezer seems somewhat prone to saying moderately embarrassing things, it makes sense that he would want to hold discussions somewhere that's not directly associated with PR-delicate organizations and communities, and where he might be more able to better control how public things are.
I hope you're not calling LW "PR-delicate"...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
