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.
It's about a surrounding society's measure of status, not about the community's. Celebrity-outsiders (high status on the outside, indeterminate status on the inside) dropping in at Reddit often get a very positive reception for example. Random-person-outsiders (indeterminate status both outside and inside) get the random person outsider reception. The drop-in celebrities at Reddit probably don't net the top ratings for the whole site, given how Reddit is huge, but a small forum that doesn't have that much inside vote activity could easily end up treating an interesting high outside status person dropping in as the most interesting event in the forum history.
I don't think Holden Karnofsky is high status as far as society goes. Outside of people with interest in Effective Altruism he's just a random person running an NGO.
