Not necessarily, Lurker. You are referring to the noun 'couple', which indeed means 'two'. 'A couple of', used as an indefinite determiner (which is the case in the title above) means 'more than one, albeit a small amount/number'. It's basically a synonym of 'a few'. Therefore the title of this blog is grammatical :)
