Quick recipe - details later:
1) thumbs up
2) subscribe to the publisher
3) watch the
video to the very end
4) [s]"friend" the publisher[/s] (no longer)
These four things will, in time, lead to about 500 more views.
5) click on the "share" button. Add it to your
facebook page, your twitter account, stumbleupon or anything that you think is fun. This could add dozens or hundreds of views.
If it is the first 24 hours that the video has been up, then you might also:
6) add a comment (on the video page at youtube)
7) add to favorites
Youtube has pages for "most discussed" and "most favorited" for the last 24 hours.
submit to reddit - this could add anywhere from a dozen to 10,000 views.
