The number of languages that do WebSockets well include what would be a small subset of "virtually every language that is used for webdev [sic] has a framework that is similar to rails". But that wasn't really the point of the comment. The point, for those who didn't feel the need to read all the way through, is that Elixir's surface level similarity to Ruby is enough to make Rubyists, or at least this Rubyist, feel reasonably comfortable, reasonably quickly. Making the Elixir/Ruby comparisons may have some annoying side effects, but they're probably good for the growth of the language.
