I think it is seriously something you need a lot of minors and hobbyists to maintain. I had a thought about a later era with some ads. The flash games era. Now if you look at game websites you'll see a lot of old flash developers who went onto "real life" reselling them. This isn't a bad thing, they take out the work of fooling around with web archives and creating a proper flash-jail but it illustrates how the web has gotten older, creators went onto 'real life' and what remains is professionalized. Of course there is nothing technically stopping you from engaging in the same as the past except other users of free time.
