It's funny how the whole page doesn't say what I get for logging in.

From the video I guess it shows me a graph view of the people? Why would I want or need that? Why is it a big deal? I haven't thought about it in depth but it sounds like a weekend student project. I have seen such graphs of many things, github commits, keyword clouds, etc, and not once did I have the feeling it's giving me more than being a nice effect. It's not a good way to do real analysis or work on daily (simple, boring bar charts for amounts or tree views for relationships are much better in my experience).

So, stepping aside from expressing my disappointment: Did anybody log in? What does it do?
