Title is so important. Subject matter is also crucial.

Videos that are current,political,combative,WTF!,"viral",scientifically geeky, RON PAUL! will naturally float towards the top 15.
Yet I still post Renaissance composers and Ranking Roger and expect them to make top 3. However . . .

Active commenting and engaged participation on the site (through interesting video descriptions or passion for the posts) are also critical to success. I have had far less time to participate recently due to moving across country and my posts are failing at an alarming and unprecedented rate. I would like to blame it on Lucky's code (and I do think that the loss of collective clubhouses has hurt somewhat), but the fact is that I am drive-by sifting now.

Title it right . . .or post that upcoming Ron Paul/Mike Gravel/Dennis Kucinich cagematch with a bad title and it won't matter how shiny the star is.
