And it has (almost) nothing to do with real estate.
They have this tool called TimeTube for YouTube. It is kind of cool. Instead of searching YouTube and getting a list, the result is a cross between a tag cloud and a timeline.
Frankly, it could just be a groovy timewaster... or it could be a great tool to search videos and find what may be most relevant to your specific needs.
I guess it all comes down to reasons one may search YouTube for videos.
Every Sunday I toss a couple of videos on my LaneBailey.com blog. I obviously have to search out videos sometimes (other times, the videos find me) and this might be a way for me to find both popular and less well known videos.
