 In the digital era, free expression and public critique is both easier and harder than in the past with print media. In the digital world, free expression means posting text, audio, and video on the Internet for others to see. Free services exist for those that want to post text, but audio and video pose cost constraints that only the professionals can afford. Furthermore, public critique requires an ability to refer to and quote other’s comments, and then add commentary around these quotations. Again, this is easy in the text world of the World Wide Web through hypertext links, but audio and video are not yet easy because of a lack of tools to easily quote from these sources. “Deep linking” into video is possible in theory but not in practice.
