Alex NedelcuWhen anti-<a href="https://mastodon.social/tags/Scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#Scala</a> people say “nothing like [drama] has happened in the Java community”, that's only because <a href="https://mastodon.social/tags/Java" class="mention hashtag" rel="nofollow noopener" target="_blank">#Java</a> doesn't have a “community”.It's like living in a village, where everyone knows each other, versus a city, where you barely know your next-door neighbours 😉To minimize community drama, pick wildly popular tech with distributed governance, maintained by large, faceless corporations but not fully controlled by a single entity (like Java or Linux, but unlike Microsoft's dotNET).
