George Carlin has a great chapter in his book (sorry, don't recall the name) all about these things.
I guess you can add: adding the word 'way' as in this is way expensive rather than 'too' expensive and also: 'these ones'.
I guess it's the result of a proper home schooling.
Finally it's way of striking back on all those other anal cavities that seem they need to correct other people's spelling or grammar.
But then, once in a while I will purposely mispill a word or deliberately using poor grammar just to give those folks something to bark abaout.
