The meta site produces a bunch of great suggestions, many of which get implemented.
Take the narcissism question, for example... Can "user profile views" NOT include narcissism please?
My guess is that some people (particularly those who don't frequent meta) won't realise when a piece of functionality has changed. So I'd like to see some sort of an indicator appear for a while (week? month?) to say "something has changed here, click here to find out what", with a link back to the relevant question, or FAQ entry, etc, etc...
