I think it's so much about the crowd who gets into those languages. But there are absolutely Java developers who are about the good times as much as Ruby developers. They're just outnumbered, but they're there if you look hard enough. I find the good people are there for every language, because the best people are polyglot programmers. I only refer to F# and Haskell like this because those communities are small. You can easily meet and greet every single developer who's publicly committed more than 500 lines of Haskell to GitHub in your entire (small) country, by going to a convention.
