Interesting to see more people who used to hang out on ##java on Freenode. That channel was horrendous back in the day with uncool admins who took pride in insulting people who were asking normal questions
These days I actually mostly hang out on Facebook Groups discussing interests like photography and music.
I also hang out on tech slack servers and have many Discord servers open. The problem I see with Discord is I join many servers that I never return to but sometimes don't leave due to FOMO :).
