Re the other: I think they feel it's contradictory for you to say that you're uncommitted to any particular language while at the same time specifically saying that you'd like a job programming in Haskell. I can see how someone might feel that there's a tension between those two assertions, but I don't see it as contradictory, nor as implying that the "About" needs modification.
It was probably just a throw-away comment, and not really worth close analysis.
(Thanks for pointing out the typo.)
