Network Effect
An economic phenomenon in which the value of a product or service increases as the number of users grows. In communications products this is expressed by Metcalfe's Law, and it constitutes a core source of competitive moats in platform economies.

The developer believes that moats come from network effects, platform connections, and compliance and system integration barriers, rather than the features themselves.
A decline in Stack Overflow participation causes the network effect to run in reverse: fewer contributions lead to stale content, and stale content accelerates user attrition, forming a self-reinforcing cycle of decay.
The network effect refers to the phenomenon in which a platform's value rises as the number of users increases, and Stack Overflow is a typical example: the more questioners there are, the richer the accumulated questions and answers, and the more answerers there are, the faster the responses and the stricter the moderation, forming a positive feedback loop.
The value of directory-type products comes from network effects—a sufficient number of high-quality entries attract visitors, and a sufficient number of visitors attract submitters.
The network effects of platform companies are divided into two categories: same-side effects and cross-side effects.
The core challenge of metaverse-type products is retention and network effects, as insufficient concurrent online users prevents the social value of chance encounters from being realized.
Team communication tools have strong network effects and switching inertia, making it nearly impossible for a single member to migrate to a new platform alone, because the value of a communication tool is directly proportional to the number of its users.
Network effects in AI products typically manifest as data network effects: more users generate more data, which can be used to improve the model and product experience, thereby attracting even more users.
The cold-start problem is the core challenge facing all platform products that rely on network effects, referring to the fact that a product's value grows exponentially with the number of users, but provides almost no value when early-stage user numbers are scarce.
