Watch Twitter Happen!

This video, which introduces the NYT's Project Cascade, is very intriguing for 2 reasons:

1) It shows people how messages are spread through the Twitterverse, or, "visualize sharing activity." (very interesting to watch)
2) I also think this will be the future of how people measure ROI - not monetary, but by actually looking at how far your message/article spread and through what connections.

The last big question is - what will these tools enable newspapers to do? How will it shape their online development? And how might it prompt them to change their Twitter strategies?
