I have to admit that wikipedia has been a big part of my internet life and is still a great way to expand knowledge (also discern sources and facts according to real and supported links). As a kid, I always wanted to have a complete set of encyclopedia which I would read a lot and stumble on many pages and information.
Since that would cost a lot of money, I almost lost hope of having a library of information that I will share to my future children. But when the age of the internet came and brought a exponentially insane source of information, it was overwhelming.
