Don't want to be that guy throwing word-turds at someone's actual work, but both ideas (making any webpage editable, and trusted err, well I guess webrings) have tried and died more than once.
I can see how webrings died when social media took over — not that I believe social media to be superior in any way — but I never understood why making webpages editable never took off. There were a few attempts, most requiring extensions.
EDIT: Chrome-only extension? Now I don't feel so bad about those thrown word-turds ;)
