The other day at CERN, one of the thing that intrigued me most was the discussion around the first webpage. Tim Berners-Lee showed us the HyperMedia Browser/Editor, represented above. What's important there is the notion of a read/write piece of software, which reminds us that the "write" (i.e. "participate in the creation of content") component was there right from the beginning of the WWW.

As a person interested in how things age, I quite enjoy the crappy sticker on the first webserver ("This machine is a server, do not power it down")
