Well, I did not imagine all the possibilities for what concerns you guys would have in order to choose verbiage sufficiently vague enough that those options would work as perfect catch-alls, but I did as for "other causes" in the comments, and I'm interested to see the concerns that people are adding like "EY stopped posting" and "We don't have enough good posters" which aren't about cultural erosion, but about a lapse in the stream of good content.

If you have concerns about the future of LessWrong not addressed so far in this discussion, please feel free to add them to the comments, however unrelated they are to the words used in my poll.
