So, sometime back in the late summer I get this letter about one of my products and I have to say, I was thinking -- "Crap, I have a stalker." It totally freaked me out at first - wait till you see the letter. And seeing as half my google searches are dudes looking for porn - I was scared.
Anyway, I answered and it turns out he's okay - nice too. He has a website where he writes funny (and sometimes very cleverly disguised critical) letters to large companies.
