I've recently noticed that the "...for Dummies" range has experienced a fairly significant amount of brand extension. Remember when it was just computer software, like "Excel for Dummies" and so on? Then they branched out into all manner of things, such as "Buying a home for Dummies", and "Cat care for dummies". But lately it seems to have gone a bit far... I was in a bookstore this weekend and saw "Breast Cancer for Dummies". Really?
Of course, nothing compares to the ambiguously titled "Building a website for Dummies".
