Not having to walk on eggshells because everything is a hate crime now, though I suppose it's more of a culture thing rather than just the Internet having changed. Still, a barrier of entry to being able to communicate with others made sure that the moronic masses of society simply went unheard instead of dictating the rules. In a way the old Internet was the first safe space if you think about it, which is hilarious in hindsight. You could do anything and say anything and either you happened to be with a crowd that understood your gripes with life or you moved on until you found that crowd. Good luck with that these days, unless you stayed clear of social media over the last 20 years like I have.
No social media was a blessing we didn't know we had. Never understood the appeal personally. I had enough interaction with people whenever I went outside. Computer time has always been me time and I certainly wasn't going to waste it dealing with Karens.
