I think website search would be more popular then video search for now, but in the future video search might be more popular when most of the answers to questions can be found on a video uploaded to YouTube, Dailymotion, Vimeo, and other video site.
I think Google video search is also useful for people who want to find Jpop, Kpop, Cpop, and foreign music videos which are not on YouTube.
Plus, watching video is easier to understand then text for some people since video uses video, sound, pictures, background music, and visual symbols which more people who are illiterate, or have a difficult time reading can understand.
I mostly use YouTube as well, but YouTube tends to delete a lot of copyrighted, violent, and more mature videos which you can easily find on non-youtube video sites when you use Google Video search which searches YouTube, Dailymotion, Vimeo, and most of the popular video sharing sites which are less strict about not allowing copyrighted, violent, and more mature videos on its site.
