internet

A gargantuan system of connected computers forming a network that spans the entire planet, witch is why it is also called the world wide web.
Or simply the thing on the screen you are reading this from.
The internet (atleast the one we know about) is entirely populated by humans (maybe),this is a very good excuse as to its state,after all humans are not the most organized bunch.It is possible to find anything and i mean anything here,including things that greatly cripple our world view and how you perceive your fellow earthlings because unhindered communication reaches the depths of the subconscious.(it is a good idea to leave your right/wrong distinguishing module off as it does not apply evenly with all individuals of Homo sapiens).

Modern human-This place has everything,including virtual AIDS that wrecks your computer.
time traveling wizard-Wow we didn't really change haven't we.
