Ahh, okay. Fairly niche, I assume? I'm pretty religious about following HN and other tech news feeds, but have never heard of "Swift NIO". While, on the other hand, I've heard tons about node.js and Golang developments, even though I'm equally inexperienced with those.

Feels like Swift afficiciandos aren't quite as good at PR as their base competition.

I'm basically still back in the jQuery, Python/Django, Ruby/Rails, Tomcat/Java/Spring, PHP/Laravel, space. I understand the comparisons and tradeoffs with those. So, perhaps, I'm fairly agnostic about what's "hot" and "popular".
