No single person can control the culture that emerges in each board, and they tend to be distinct and idiosyncratic, and the distinctions are (in aggregate) the strength of this system as a whole.

However, every single person can (and does) influence the culture on each board. And that is best done one way - to have a mind-set (and quality of post) yourself in the way that you'd love to see others having (and writing).

That includes:
1. Writing posts involving thought.
2. Keep your own intellectual quality/quantity average your posts as high as you can. Note the denominator - there is no need to post too often, the community have a history of returning not just for the latest post but also for reading back on past posts also. Treat the place half like a library, half like a community.
3. Marking posts not related to the board theme as 'OT:'. This thread is no exception - it should have been marked 'OT:'.
4. Tolerate, try to see quality amongst the weeds, however if it becomes too much, use the Ignore feature. Give critique as that is largely how knowledge progresses (versus confirmation). However argue with the idea, not with the person. No matter how robust people seem to come across, assume that they are much more sensitive than you think and lean in the direction of imagining everyone you are responding to as at the dinner table in front of you. RationalWalk left not because of the lack of ideas (at the time), but because of a lack of sensitivity (at the time). Be genuinely kind, it goes back centuries and works.

The Berkshire Hathaway board has 25+ year momentum. If Tesla comes up too much, remind them (sometimes) to mark their post OT, and every time you do that, include a link to the applicable board (in this case the Tesla board):

Shrewd it!
