Again, fascinating. And I do very little real-life socialising. But on the whole I think I do a good deal more talking than typing. ETA: On second thought, I'm not sure why I thought that. Something made me overestimate how much talking I do. Probably the fact that I used to do a lot more, and certainly have done immensely more talking than writing over the course of my life so far.
There's been a recent heavily upvoted and profusely commented post about things people want to learn. It's close to having so many comments in a single day that it should probably have a part 2.
However, the subject seems to inspire thoughts about what *other* people ought to know, and while that's got a good bit of overlap, it's emotionally rather different.
So, what do you think other people ought to know? Any theories about why they haven't learned it already? Any experience with getting someone else to learn something when it started out as your project rather than theirs, especially if the other person was an adult?
