Generally it is unpleasant dealing with unpleasant people. Sometimes though, if a question has been asked many times or if people end up talking past each other, hostility can arise and the ones answering can start becoming a bit snarky. I would say #haskell is usually very friendly, but no community is perfect. I noticed the above once and it was actually quite easy and simple to fix it. I simply joined in on the ongoing question session and started implying that we should perhaps answer a bit more nice to the newcomer.
