Wouldn't also be fair to point out that so far, we only have video/caps/i,ages from the boat rides to the start and one image of some of the teams ar Heathrow?
Came angles, image quality, lighting, all can affect whay we see in different ways that sometimes the same person looks like two different people. Yhis is where information other than images is useful. such as the social networks and search rsults, right?
I have a concern that we're becoming too dependent on tweets, because there are still the possibility that local media (especially in languages other than English), and bloggers will be posting useful data that can help fill in the pictutr.
