Not straight spelling or grammar errors. Just old fashioned, mashing your keyboard too fast, just like your grandparents did.
  1. amd
    "Amd" is trying to be "and" and is soooo close it makes me want to give it a hug and tell it it's doing a great job.
  2. waht
    "Waht" makes me giggle and then I can't take the question seriously. Docked because it is dangerously close to "wat," which can go straight to hell.
  3. ot, etc
    Got 2 letters and you just mixed them up? Solid, solid typo. Not flashy but gets the job done.
  4. teh
    Teh worst.
