I don't mean to be rude but I'm not sure why you would use this over youtube itself.
a few of the problems
doesn't include date of upload
can't sort by date
Search isn't intuitive - only selects exact match of order of words in title and only words at the beginning
Example: metrodome collapse, dome collapse, metrodome snow all = zero results but get plenty at youtube include what you are looking for (the collapse of the roof of the Minnesota Metrodome today)
but - Metrodome roof (the 1st 2 words of many of the titles - Metrodome roof collapse) does yield results
Oh what a beautiful morning = many results (song from movie/play Oklahoma)
beautiful morning = zero results
