Product I wish existed: Google Doc to Website
It would use the new “tabs” feature on Docs to make a full webpage:
– Each tab is a menu item.
– Each page is content area.
– Just update your Doc and site reflects it.Would be easiest way for average person to maintain a website.
He’s referring to this new tabs feature in Google Docs 
Similar to Neville’s idea is Sheet2Site, which turns a Google Sheet into a website.
That was earning $10K per month a few years back 
I suspect something like Doc2Site could earn even more than that.
