Re: Users should pay to use Facebook
You clearly have no idea what you are on about.
Gopher was a protocol, it even has an RFC if I recall correctly. The only 'charge for it' was for some specific implementations of the server software, just like many HTTP server implementations are charged for. It was completely free to use, just like WWW.
What killed Gopher was that it had no provision for slapping a big animated GIF advert in the middle of the page and earning money from views and clickthroughs, hence it got trampled underfoot in the stampede to cash in on the web 1.0 bubble.
