Viddler - tags inside video makes for better instructional design

You have heard of YouTube, Google Video, and other Social Video sites. Now Viddler enters the scene with a unique twist. Viddler makes search results relevant since Viddler searches INSIDE the content of videos. A user can tag a video at any moment inside a video with a key word so that when you search for something specific, you can go right to that specific part of the video instead of having to watch the whole thing.

This is a nice tool to be incorporated into video for online instruction. For example, instead of sifting through an entire video lecture on Maslow's Hierarchy, one could easily search for and identify the part of the lecture on "Social Needs" if it were tagged.
