This blog touches on why Elixir is doing so well-- it's easy to extend and add to the language, pull requests are welcome and (most of the time, anyway) the Jose appreciates and integrates additions to the language. (He once rejected something that I disagree with, but on the balance he's doing a righteous job.)<p>In fact, it's the only language I've contributed to. In large part because the bar is so low and the process is so reasonable.
