YES! Too many people abuse English in such a manner.

Also:
  • Using "advise" as a noun; It's really a verb! "Advice" is the noun, even if you are from the UK.
  • Using "Infinate" and "definate", instead of "infinite" and "definite", respectively.
  • "Asterik" or "asteriks" instead of the correct spelling: "asterisk". It's quite simple to say: ASTER - RISK.
  • "Me to!" instead of "Me too!"
  • Sentence fragments. :rolleyes2 (Just kidding, haha! Guilty as charged. )
