I think you already launched your video, but I wanted to let you know that I normally do more keyword research before I pick a title.
YouTube now has its own keyword research tool.
I did some training on this during a recent Tuesday night show. I think it's in the show archives.
I make sure I pick some good keywords with decent traffic, but not too much competition. Don't forget that videos are extremely valuable long after the viral effect is gone. They have a chance to rank in the search engines for years to come. I have videos on extremely high volume "money" terms ranking in the top 4 on Google more than a year after I posted them. Without the right keywords in the title that would never have happened.
