The way I understood is, if you’re hyper-online and very consumerist, you’ll want to onto the train fast, and get off it fast so you would be deemed as a “trend maker” rather than “trend follower”. I’m not sure if I’m making sense, but it’s a bit more visible within Tokyo/Shanghai subcultures. It was less visible to me in Vancouver, where there’s a single main culture (everything outdoor and outdoor related) and not participating is also “not cool”.
