It will be web 7 - no .0 needed 'cause it'll be the final episode. Why? Well, 7 is a special number, holy some would say, at least prime and - important - the day of rest. It took 6 symbolic days to build the earth and sky and all that moves in, on and over it and with all that done the 7th day is declared a day of rest. It'll take 6 webs with all that crawl and crap under, in and over them until the 7th iteration when someone says "leave well enough alone" and walks off to water his tomatoes or floss the cat. Others will wake up from the hypno-daze induced by the latest addition to Web 6.666, notice there's a world out there full of tomatoes in need off watering and cats due flossing and find they much prefer life there over being caught in that web. When the tomatoes' and cats' needs have been satisfied they let their friends and kin know through something eerily resembling Web 0.1 - their Web.6.666 kit doesn't work anymore since they missed a few upgrades during their absence - about their exploits and suddenly their eyes are opened wide. This is what it is all for, a means of communication. Web 7, the final frontier which looks strangely familiar.
