I'm familiar with C and Java, and I can build viable projects in Python/ Django. To expand my understanding I'm looking at Go or Haskell next, although I might take a quick spin through Rails to see how it compares to Django. I'll continue to build the projects I care about in Python, though, because I'd rather go deep with what I know than spread myself too thin. I expect to become better at Python by dipping into these other languages.
