This website made me laugh. 🙂
It would seem that someone has such a strong aversion to definitely being misspelled that he or she created an entire, albeit simple, website dedicated to educating people about how definitely should be spelled.
My first thought: Who would spend the money and energy to set up such a site?
Regardless of that, however, some of you may find the site a useful tool when a friend seems to consistently stumble over the word.
Hope it gives you a laugh, too.
