That's advice to meet activity partners, not friends. Think of your closest friends. Did you set out to meet them by looking for people with their exact interests? Maybe you did and you and your friends are part of a scene, but I'd bet most people did not.
On advice like yours, I started a niche club and ran it for 3 years. When people join your club, they're not there to meet you! They're joining to participate in the club. Now you're in the awkward position of responsibility as the club's host/organizer, with the additional distance between you and the other participants.
