@rusty__shackleford Broadly speaking? For most people, the wall between online and offline life thinned and disappeared. There became more advantages to self-representing as who you were IRL than in keeping your dog-anonymity.
The threats didn't change, but the boons turned out to be huge. People collaborated online and that success transitioned to their real lives. Folks met other human beings in chat rooms and fell in love and got married. Bloggers parlayed their words into TED talks. People found business required them to represent themselves accurately for legal (or simple common human behavior in the offline business world) reasons. Facebook gave a generation of college students an opportunity to self-represent as themselves and their world didn't spontaneously combust as a result, on average (I think of all of these things, that's the one that had the largest impact on shifting online culture).
There's still an underground that stays anonymous, and God bless 'em. But as with most human societies throughout history, we tilted toward "reputation matters" and began to assume those who stay anonymous have something to hide that they don't want attached to their reputation, which is default-suspicious.
