The Google comparison is comical. You are wildly over-estimating how well known Erlang is, even in the dev community.
> Do you really decide whether you'd learn a language by looking at its website?
Most devs learn a new language when it helps them solve a problem. Anyone who needs to solve the problems that Erlang addresses has already at least looked at Erlang.
This thread was also directed at those who have never used Erlang. Starting with the Erlang website makes eminent sense.
Specific example :
Compare the Erland and Rust websites. I've never used Rust or Erlang. I can confidently say that the Rust website does a better job of familiarizing a new user with the language. It's not just a matter of the Rust syntax being C-derived, either. It's simply harder to find any useful information on the Erlang website.
Rust :
* code sample on landing page
* comprehensive tutorial linked directly from landing page
Erlang : * no code on landing page
* "quick start guide" which is basically a link to a non-free book
* Getting to actual code requires 3-4 clicks from the landing page
* e.g. Documentation -> Course -> Sequential Programming
Conclusion : The Erlang website isn't as useful as that of at least 1 other non-mainstream language.
