To illustrate a few of my pet peeves in spelling, may I say:

I would of told you that some folks are just loosers,
And the Internets filled with poor English users,
But noone ever said its easy
To express yourself as non-cheesy,
Without you become a language abuser.

Yeah, I know it's not much, but it's off the top of my head, so I couldn't be exhaustive in the listing.
