I can't think of another way someone would find my CouchDB post unless through Google -- and, as the other commenter said, I don't expect people to enter my site and start reading everything there.
I think understand your motivations, but I think your goal (a live-editable website) is not a new one. Products like Squarespace, Wix, Weebly and others are targetting this market. I don't like the idea, because to do this you must either (a) limit the ability of the user to modify the website, making it choose from predefined templates and letting him customize only a little; or (b) make him write his own HTML and CSS.
These providers I mentioned are kinda fighting against this trade-off by creating more and more themes and enlarging the customization space, that is taking time and human resources, and the result is not good -- I don't like it --, but they are too much ahead of your service. You should have a better thing, a really different feature, innovative, as you said you are "rethinking" blogging I thought you had this, but I don't see it.
Ok, maybe I didn't understand anything at all.
