Another interpretation, since these are voluntarily reported on a CV, is that the people citing OS X and Haskell are more likely to be trying to differentiate themselves. They want to be seen to "Think Different." In the likes column, they add a prestigious and difficult language or an OS associated with an exclusive brand. In the dislikes, they put items that are seen as mainstream.

While people who write c# code on windows tend to take it easy...

Neither C# nor Windows is on the graph the parent comment is referencing. On the other end of that graph is linux and scala.

You're both wrong. The graph the GP references is solely the top 12 most polarized. You need to go down one more char to get the opposite end (It includes asp.net but not C#).

Yeah, you're right. My apologies.

Hey, that's me! And I do hate a lot of things... including Haskell and OS X sometimes :)
