YouTube has become somewhat ubiquitous on the internet, and in popular culture generally. Web 2.0 applications which encourage people to make and share things are often not very specific tools, as such, but are broad platforms. Without the 'amateur' content and contributions, YouTube would be much less popular. YouTube is a platform which offers a framework for participation, but which is open to a very wide variety of uses and contributions, and basically agnostic about the content, which means it has been adopted by a wide range of users for a diverse array of purposes. People spend time creating online content because they want to feel active and recognized within a community of interesting people, and because they wish to express or display aspects of themselves and their interests.
