Done more for advancing access to information than anyone else in history since Gutenberg? Now that is a perfect example of the pure unmitigated bullshit surrounding the likes of Jimbo and Wikipedia (also Facebook, Twitter, Google, etc).
How much would Jimbo have contributed to the access of information without Tim Berners-Lee and Vint Cerf? No web, no wiki. No internet, no wiki.
And, that's without thinking about all the people involved in the invention of better printing techniques, book binding, magazines, newspapers, radio, film, TV, etc that did more for access to information than Wikipedia ever could.
Oh and Gutenberg didn't actually invent printing, it already existed. He invented movable type which made things easier and cheaper. Someone else would have come up with the same idea sooner or later.
