Is this your site as well?
Thanks for clarifying, and great work!
Do you plan to keep it up indefinitely or open-source it?
It's running on a single Heroku dyno with the free MongoHq service, so at some point I'll have to figure out what to do when there's more than 512MB of documents stored, but for now it's running indefinitely.
Is there a directory of sites like this somewhere, by the way?
http://hnshowcase.com : visual preview, filtering, social integration, etc.
http://showinghn.com : minimalist list based on /newest polling
https://twitter.com/JustShowHN : Twitter feed based on main RSS

I'm going to try to get this working for JSON Blob API's documentation over the weekend.
Other than that, I like it a lot. Very cool side project
