Existence ≠ Notability := Bad editing experience.

Well, I'm not convinced that we don't already have some form of CV-space on wikipedia - actually every registered editor has a user page, as well as a talk page.

The point I was making is that notability as a reason for exclusion is a great way to upset a lot of people who enter into the WP world. Actually, the requirement for RS as well as an avoidance of COI should be enough to prevent self-authored vanity WP Pages.

Likewise, I know of plenty of people who do indeed have WP pages. Lots of publishers now actively encourage new authors to generate a WP page - the publications model that WP is currently obsessed by implicitly encourages such activity.

I agree. As topics get written on, the amount of 'notable' people left to write on shrinks, by any objective definition. If someone has an article deleted, or flagged for deletion, I suspect he'd be unlikely to try a second time. It's a chilling experience.
