When I taught on ground, I often posted things on my office door--cartoons, articles of interest, and pictures. Since I only teach online these days, it seems logical to have a virtual office door where I can post these kinds of things.
The VE Blog tends to focus on work stuff (conferences and calls for papers) for online educators, but there are also pages for Podcasts for students. Note that "Student Resources" is probably where students should start.
The current picture on my virtual door is from a church in Girona, Spain. Notice the gargoyle is upside down, facing down, rather than upwards toward heaven. Learn more about Girona's Cathedral Witch.
