Wharton students tell you who your best friends are (opens in new tab)

The OAuth flow is poorly done. It's supposed to be in an iframe/popup. Instead the OAuth window is full frame and I couldn't find the OK button on first look

Also, why does it need posting rights?

EDIT: Got the list of friends. Totally incorrect. People I rarely interact with are in the top of the list.

One thing is you need to:

a) explain what this is a little better (how does it work)

b) have an about page, team etc.

c) inform people that when they click on the link they are going to either have to be already logged into facebook or that they will have to login to facebook.

I didn't try the product because I have no clue what is going to happen or what data you will get from facebook about me.

The site was also slow to load. I'm not sure if that's transient but thought I would mention. (You're not using godaddy shared hosting are you?)
