It was only a matter of time. I wonder how well it works. I'm surprised this didn't come from some other company (but who wants to bet Google is not coming out with the same thing this year?)
I am not even wondering much about a business model - who wants to upload all of their images again? Am I missing something? Is there anything these guys can do except get bought by Google or Yahoo!?
I am thinking of the implications of easy searching of images for faces and text.
On the other hand, this is not new. This kind of stuff is being used already with cctv video. And people can be recognised from their gait cycles. I guess what surprises me is seeing this as a mass-market service, or something aspiring to be one.
