I've made this remark before, but anyway: Imagine you're a newbie to Wikipedia. You end up there from google, clicking straight to http://en.wikipedia.org/wiki/Ian_mckellan . Now, tell me, what can you see on the screen, as you read the article, tells you that you could *right this instant* edit the article to fix any changes?
Well, without trying to undermine your general point, I have to note that the [edit] links at the top of each section are a pretty good hint.
Mind you, the prominence of the "sign in / create account" link at the top of the page may be contributing to the assumption that, just as on many other sites, one must go through a registration process before being allowed to edit. Maybe we should add the text "(optional)" to that link?
