There are sites covering every topic imaginable. If you want any information at all, you simply have to look it up on the Internet. This has always been true to an extent, but the increase in Internet population into the hundreds of millions has led to a dramatic increase in data available on the Internet. If you want lyrics to even the most obscure song, a recipe to even the most rare dish, countless facts and information on planets, artwork, or any other conceivable topic, a mere link to a search engine and typing a few words into a form will yield immediate results. One of the phenomena that exist within a culture without any form of money, with almost total equality among its denizens, and that acts on information alone is what happens on the Internet.
People put content in many forms for, seemingly, no reason.
People make archives without any commercial reward, and when asked why they did it they really would not be able to give you an answer, except toil only for self gratification, without any other real reward. This is what people do on the Internet because it is the only thing that they can do. However, the flood of people is not all good. UNIX is still the standard, and UNIX will continue to be the standard for years to come. However, in spite of this fact, the Internet has made a stunning transition from obscurity to banality in just a few years.
