Much of the growth in the ecosystem is "false prosperity": lively but not sustainable, much discussion but little usage, high exposure but no reuse. True prosperity must be able to translate into usage density and user reuse. If the ecosystem can continuously enhance usage density, allowing users to complete more closed-loop actions within the same ecosystem, growth will be healthier.
When assessing a project, you can look at the "reuse signals": Will users reuse it? Does it form a fixed path? Are they willing to recommend it to friends? These signals are more reliable than short-term data. Projects that can convert liveliness into reuse are often more durable and worth following in the long term.
