I just tried it, and signed up. Process was painless, went from the homepage, to the "how does it work" button, to create an account, paypal, and back.

Once I registered I felt a bit let down because there really wasn't much to look at. It would be nice to see examples of other people's twitter feed summary. Show me a screen with 12 faces of popular people I can click on. So I know what to expect.

Can you try mine? http://news.ycombinator.com/item?id=2689356
