I watched this video called the “100 Famous Rock Guitar Riffs”, the video was made by a guitar teacher and session musician. Not only is it a good watch and as a guitarist I know that trying to remember all that in one take is well hard, but it has had over 340,000 views of the video. Wow! that is a load more than just having a website or even placing an ad somewhere. The youtube page links to his website so people can see about him.
If you have a service or product that you do, it may be something to think about, doing something that is fun but will attract alot of attention. Start thinking about how to promote your service using social video.
