Could it be that, because people are online more and communicating in person less and less, that actual in-person meetings are fraught and awkward? It's a lot easier to just have "online" friends to whom you can present your "best" self, and only see their "best" self in return (photoshopped, carefully edited comments etc.)

Part of the problem, yes. I also find people unwilling to put in even the basic effort to make and maintain friendships, offline. It is easier to text than email, it is easier to email than call, it is easier to call than meet in person and so on...

Things are bad for men than women, from what little I see around me. Broadly, I find people are more willing to help women than men, all else being equal. Maybe this is why men's lifespans are shorter than women's? Men are expected to "man up and shut up", whatever that means. So they don't seek out friends, don't speak up...
