cool service, I hope it remains up so we can depend on it.

Currently you can accomplish the same thing using Yahoo's YQL, if you'd rather trust a big company to stay up. Here's an example: http://y.ahoo.it/b7rnO

I'm using it on my website to parse my project's history.json file: http://ruhoh.com/latest-updates/, check the source on that to see how it works.

Be warned that YQL transforms arrays containing one element into strings =/, terrible I know but it works.
