As an avid Elixir user, your comment got me thinking about how and where I look for help. I realized that it wouldn't even really occur to me to use Stack Overflow for answers regarding Elixir, as the other platforms you mentioned tend to be so active and well suited for that purpose.

This isn't to say that I wouldn't use SO for other purposes, as I actively visit the site for JS/PHP content. Anecdotal evidence to support your insight by all means, of course.
