With most of the main contributors having left and no new ones emerging (except for an occasional post by Swimmer963 and So8res discussing MIRI research), this forum appears, unfortunately, to have jumped the shark. It is still an OK forum to hang out on, but don't expect great things. Unless you are the one producing them.
I don't think that's necessarily the right conclusion. In general, the quality and quantity of posting here seems to wax and wane over time with no strong patterns to it.
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.
