{ {_user} } should render as the current user's card, linked to their card.
Also see easy personal card creation.
let's implement this in inclusions but not links. Links are cached, inclusions are not. So you can't really make it work in links, but inclusions should be awesome. if you need a link, you can do view:link.
this would play well with our new community features
Useful for documentation at the very least.
Raises an odd question of what to do if someone puts +_user in a form.
As long as it's done via inclusion, it shouldn't be weird at all.
