Free Online Video Editing Sites

ExtremeTech has posted a review of 5 websites that let you edit your videos online for free.

"Some people would be surprised that you can edit photos online without locally installed software, but surely video editing is too resource-intensive to be done over the web, right? Wrong!

We tested the following: Cuts, Eyespot, JumpCut, Motionbox, One True Media."

The Reluctant Online Professor

"...when I was asked to put my course online, I felt quite unprepared ... I started the experience with great reluctance and trepidation. Much to my surprise, I finished it jubilantly. It turned out to be one of the best classes I have ever taught."

A refreshing example to read, especially for others in a similar position, but also for experienced online instructors.
