After the huge success of Google Instant, here come the YouTube Instant. Well, it is not an official release from the Google labs but a brainchild of geek who designed a site with the features of Google Instant for YouTube.
But hope that soon YouTube Instant will launch officially especially since the man who made this just got offered a job at YouTube for this genius work!
