I can't speak about web framework but at Status (Nim's [main sponsor](https://nim-lang.org/sponsors.html)), we live and die with network programming. We are building a decentralized ecosystem with a focus on the infrastructure side, messaging at the moment but addressing storage is planned.
Most of the backend codebase in production is in go but we are [discussing](https://discuss.status.im/t/nimbus-on-mobile/1370) replacing parts in Nim. And all our code is open-source: [https://github.com/status-im?utf8=%E2%9C%93&q=&type=&language=nim](https://github.com/status-im?utf8=%E2%9C%93&q=&type=&language=nim) Anyway that means that there is an active company with strong incentives to make network programming in Nim a happy story.
