I'm not sure what the deal is with all the criticism on here. Yeah, it wasn't all that hard - but that's the point. This is a good test of a basic level of skills one needs these days to be a Web developer (Firebug, parsing HTTP headers, deciphering Javascript, jQuery). And, it was fun.

All the hate reminds me of the quote: "Criticism is an indirect form of self-boasting."

So, if you read HN and you were able to get through step 5, congratulations! You're at least an average Web developer.
