Ah, that makes sense.

I didn't really see this article as being interesting from the "oh look, a reddit!" angle. I thought it was a good article in that it showed how to do a lot of things in Clojure: Java interop, a basic Compojure use case, and deployment with Leinengen.

This discussion reminds me of Fred Wilson's article about bit.ly "That's only Ten Lines of Code"

Sure, you can replicate lots of sites but to me Reddit wasn't great because of the tech, it was because they had built something really zeitgeisty that people liked.

Not to mention the hard part ... building a community.

And features such as comments.

Slightly on topic:

How would you attack the "query performance, cacheing, scaling, etc" problems?
