Ahh, that makes sense. This project was a really interesting case study in how people move through the web. We had quite a bit of publicity for this early on, including some write-ups in print publications, major blogs, television, and radio shows (offline media generated virtually no apparent traffic). I also posted a link to r/economics when we first launched the site. Despite all that, one of the most enduring sources of traffic (other than university web sites, where professors post the link on Blackboard, etc.) has been Marginal Revolution, which is a relatively niche blog. I'm not really sure why.
