Before trying a nostalgia network, most people want to know one thing: can it actually surface the right classmates without turning into a generic social feed? Classmates is positioned around school-based discovery, giving former students a place to look up people by campus, class year, and shared history instead of starting from follower graphs or public posting habits.
The useful way to judge it is as a reconnect network, not a broad social app. Check how well it narrows searches by school identity, how much participation is required before profiles become useful, whether outreach feels private or performative, how reunion activity is handled, and whether repeat visits come from new matches, memory browsing, or ongoing class updates. That lens matters more than raw member counts.
