I have one of the original tilde.club accounts. It was a fun moment, when a bunch of folks re-experienced (or experienced) the first time the pleasure of a shared Unix system. Just like the Old Ones had in college. When finger was social media, and "who" worked, and if you were really cool your .plan was a named pipe. It worked because it was nostalgic and because its sysop Paul Ford is a first class human being. Never occurred to me it'd be an idea with longevity.
