It's "If I were the CEO of Posterous."

And it's one of those cases where knowing a foreign language can help you think about English a bit more clearly. It's mostly vestigial in English (which is why "if I was rich" is so common), but in a language like Italian, it's much more widely used (I think that ..., I believe that ..., I want ... and similar sentiments all require that you use the subjunctive), and it has obviously different verb forms: "penso che sia" instead of "penso che e`". It appears from that wikipedia article that Spanish is similar.
