Perhaps the author can use the already submitted questionnaires to see which questions correlate heavily, so they might be merged.
The only language I know from this list that I wouldn't recommend wholeheartedly to someone else is Java, and that's just because I know C#.
A bunch of languages I know very superficially, and just haven't learned because I didn't like their superficial qualities. Anyone here ever mastered (not just learned) a language that they did not like at all? I don't like Java all that much, but it is not absolutely terrible.
(From this list I am comfortable with Ruby, Haskell, C#, Java and Javascript, less comfortable with C, C++, Scheme, Python, ASM, Matlab, VB, PHP)
