Please solve it and let me know if it's dumb or boring.

I've been fruitlessly trying to find a community like security Twitter circa 2008-2012 and failing :/ Maybe this will be closer to that? Now I'm trying to re-add everyone I've tried to keep in touch with via Mastadon, Slack, Threads, Discord, etc. and it feels difficult.
