Where I know anything about the field, they look good to me. The nonprofit one made me go "AAAAAAAA WHY DIDN'T YOU TELL ME THIS 25 YEARS AGO (because I was too young and stupid to even think of asking)" which made me think well of it.

This is the monthly thread for posting media of various types that you've found that you enjoy. I find that reading the sequences makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this.

To see previous recommendations, check out the older threads.
