There is nothing quite as annoying and completely rude as when someone sends out emails devoid of proper capitalization, punctuation and at worst of all, proper English. I've found that top executives are the worst. Don't even get me started on people with Blackberrys. The good people at c|net (via The NY TImes) have a good write-up about this very thing. The examples are humorous and hideous.
