It truly is an end of an era. I popped in every so often to check the temperature and was rarely disappointed by the level of crazy pervading it. Amusingly, despite it having such a massive influence on internet as a whole including its lingo and memes, my wife did not even knew about it existed until today.
I do not think it will be missed by many, but that kind of hole does not exactly disappear without a trace.
After leaving when it got too shitty, I would go back once a year or so to check the racism in pol, see if maybe b was back to doing things instead of just porn, and read the plainly undiagnosed schizophrenia on the paranormal board.
Like you said, not a lot of people in my life have any idea what it is, but it does hold a special place in my heart. It started when I was trying to establish my own personality, and it provided me with a safe avenue to try out different "me's".
