As we know, There are known knowns - such as click bombing and clicking on your competitors ads. There are things we know we know, such as people using proxies to evade detection We also know there are known unknowns, such as how many clicks from a single user is legitimate That is to say we know there are some things we do not know, for example will yahoo ever have a chance in PPC again? But there are also unknown unknowns, like will Sergey and Brin buy a submarine The ones we don't know We don't know. like, is it evil to make so much money?
what the hell are you talking about, "like will Sergey and Brin buy a submarine The ones we don't know We don't know. like, is it evil to make so much money?"
In the UK we call this sort of post a 'piss take'. The 'known knowns', 'known unknowns', 'known unknowns we think we know' should be a bit of a giveaway!
