This is the first I have heard or seen anything about a trailer. A Trailer for a book may be a great thing. In that YouTube is very popular, this could be an excellent way to market a book.

Any social network site can be beneficial, however, they can also be a huge waste of time and energy if not utilized with a specific purpose in mind.

I recently posted an article on my blog about social networks, which in a sense, YouTube could be considered a social network. Of course, different than the MySpace type sites, but definitely a place people have found great marketing opportunities.

The man who did the Evolution of Dance received 57,000,000 (yes million) views. That is incredible. He opened up a lot of opportunities because of the number of visits.

As with anything, no matter how slick and leading edge something is, what is the plan to drive people to see it. How can you get viral marketing out of the Trailer strategy.

I am going to check into it because it definitely seems viable.
