Not just you. Even within the confines of Twitter, I feel like I used to at least make virtual friends much more easily.
But, of course, a lot about me and my behavior has changed, too. ¯\_(ツ)_/¯
I also feel like there used to be more spaces online specifically designed to facilitate this. Now they've all been turned into terrible smartphone-centric Tinder clones. And of course, society continues to atomize at alarming rates... I don't think I've changed that much in the past decade — I feel like everything around me has radically shifted.
