About 10 years ago I was a regular on a small local forum. I met many good friends there, most have simply vanished but the few that I remained in contact with have been with me since, despite the forum's demise 8 years ago.
Presently, one of my best friends happens to be a person I met there, and another person from that place happens to be my significant other (for six years and counting.)
Thinking about it, it's insane just how much some obscure small forum I joined on a whim back then impacted my life.
