Back to you, Jeff.

We are at the point of convergence of three equally important developments: technology, time and place, and people.

First, in tech, research in this kind of market algorithm has only recently become hot, and the clarity of technology that we use for AV has only recently become readily available.

Additionally, we get to benefit from the last 10 years of Web 2.0.

In time and place, we couldn't be in a better location here in Cambridge because of the recent announ- announcement of EdX.

And we are lucky e- enough to have the right people and resources available to us through the i-lab and our mentors, the different skill sets that our team members bring to the table, and the fact that our user base, the students, are already immersed in social networks and are ready for a platform.

This is the homepage of Crimson.com. Our MindCloud algorithm delivers the largest possible network of effective tutors by leveraging peer-to-peer teaching.

Hilton, for the stay.
