Here is the periodic sampling from my del.icio.us favorites list. This time I chose the tag "YouTube," as it is being broadly used for instructional ends. It is also a flexible tool. YouTube videos can be embedded into PowerPoint and SlideShare presentations as well as webpages, social media sites, etc. Here's what I found I have:
