Videos are a great way to more effectively engage and communicate with people.  Adding pictures to audio increases people's retention and in today's fast paced world that is priceless.

I've had great success with adding video to websites and seeing the search engine rankings climb.  Of course, there is a huge amount to learning, testing and measuring that has gone along with this path. Finding a great camera (Aiptek GO HD), building more storage, video editing and transfer capabilities.  I love www.youconvertit.com as a way of changing video files from one format to another.

Posting the videos to websites such a www.youtube.com and playing them from your webpages is great.
