Personally, I have a single language pet peeve: Definate. Its definite! It comes from the word finite. People suck.
What we need is a completely phonetic alphabet, fuck q, c, x, ph and all the redundancies present. However, people who know a language become uncomfortable with its misuse and so seeing someone write quick: kwik hurts. The great part is, the alphabet would apply to all languages which would make learning a language a bit earlier.
