I'm not a professional, but I've been playing with memes for a while and have a rough idea of which projects "look lively but are actually hollow." However, the recent rhythm of @bitdealernet is completely different from those fleeting things. Because it doesn't rely on hype, but has games, a launchpad, and trading scenarios, all of which are genuinely being played and used by people. I tried it myself, and the whole ecosystem is fluid, rather than just an empty page hanging there.
