I started to have a look, but I don't see a way to preview the content of the site without creating an account. I don't know of many online discussion forums that follow this pattern. HN, Stack Overflow, and even Experts Exchange allow you some sort of access to the community (read-only) prior to signing up. Experts Exchange is actually a great case study in the distrust engendered by walling off your content behind a sign-up requirement. Stack Overflow has taken off like a rocket. I can browse every bit of user contributed content on their site without creating an account. Experts Exchange has a sizable community of people who actively dislike them. I think SO has the better model.
