I think this is good idea too!
We have several polls here (see the polls tag) however, as pointed out by @adolfont, one of the disadvantages of polls on a forum is that users can see answers by others, so may be influenced by them.
I agree that an official Elixir survey like the Rust and Go ones are the way to go 
(and that we stick to more general or ‘fun’ polls on the forum).
