Their first release is Animoto, a web application that automatically
generates professionally produced videos using their own patent-pending
technology and high-end motion design. Each video is a fully
customized orchestration of user-selected images and music. Produced
on a widescreen format, Animoto videos have the visual energy of a
music video and the emotional impact of a movie trailer.

This presentation presents a historical view of hypertext looking at pre- web hypertext as a domesticated species bred in captivity, and arguing that on the web, some breeds of hypertext have gone feral.
Post titled, By the Numbers: How I built a Web 2.0, User-Generated Content, Citizen Journalism, Long-Tail Social Media Site for $12, 107.09, includes a slideshare presentation.
