I have a current feeling that for a project to truly develop in the long term, relying on just one aspect simply won't work. Solid online community management is the foundation; it requires genuine interaction and accumulation. At the same time, community participation in building is crucial—when users are truly engaged and involved, their sense of belonging becomes very strong. But these alone are not enough; offline promotion and publicity must keep pace to let more people know about it, thereby creating real influence. These three aspects are interconnected; missing one will leave regrets. From what I see now, successful projects are generally those that coordinate these areas quite well.
