The thing I miss most is LiveJournal. Sure, over time it kind of failed, and later having data owned by possibly nefarious new owners didn't help reputationally, but what I loved was having a small, approved set of people who could read, and getting to know other people in long form, where writing was the primary draw, rather than links, brags, and ads, like social media has become. I miss the very internal nature that the platform allowed, but it was a more naive time, where the idea that whatever was there would inevitably become public wasn't a barrier to intimacy.
