In particular, Flickr epitomises the spirit of Web 2.0 and how copyright (and inherent intellectual property) has evolved for the web. In addition to social networking by sharing your creative ideas, endeavours, Flickr also allows you to share your content with as many or as few restrictions as possible via a Creative Commons license. (Another aspect of Web 2.0 is that you can follow the addition of new content and developments uploaded (by individual) via RSS feeds at the bottom of that individual's page.)

"[Lessig] regards extension of copyright as anathema to the YouTube generation and a brake on economic growth. He also thinks it is against the US constitution, which states that copyright should be "limited". The original limit has been extended from 14 to 70 years after the death of the creator, and Prof Lessig points out that one of the main corporations that lobbied for this, Disney, cut its creative teeth by raiding the public domain for works from Snow White to the Hunchback of Notre Dame. If the current term for copyright had existed then, it might have suffocated Mickey Mouse at birth." http://www.guardian.co.uk/commentisfree/2008/oct/22/intellectualproperty-copyright
