YouTube and Webcam for instructor presence

I post a weekly video for my fully online classes to help establish instructor presence, which is one of those best practices for distance education. Initially I thought it would be tough to do but the use of a webcam and YouTube's easy basic editing tools make it a breeze. The caption tools in YouTube are especially useful for short videos, which include the ones I use. For longer videos, especially instructional ones (like the one embedded on this page), I use Camtasia Studio.
