This is one of many short video segments which will be added to the Digital Tipping Point (DTP) archive.  This particular series of video segments features the very entertaining Caitlin Hill. Caitlin is included in the Digital Tipping Point Video Collection because she personifies the digital tipping point in a number of ways. First, she has used Free Open Source Software (GNU Linux) to create an internationally acclaimed video persona called "TheHill88"; and yet she didn’t even realize that she was using GNU Linux, because she was using it as a service delivered by YouTube. YouTube runs its video sharing service on top of GNU Linux, and, as of this writing, has risen to dominate not only on-line video, but in fact has entirely changed the video and film industry in less than two years of existence.
