I recently found myself wondering, why big sites such as Facebook, Google, Github etc usually aren't using EV SSL certificates? It probably would make non-technical users trust the website more and perhaps make them more aware of phishing (eh, I don't believe in that myself, but it's still nice to dream...), and it's not like they can't afford it.
