Hi, I always loved the JSON's amazing ease of use. There's no need to parse it with SAX or DOM cause there are already lots of programming languages come with built in encoding, decoding support. So I developed a converter which is called jsonMe(http://www.jsonme.com) that converts RSS to JSON. If you need a rss feeds as json, feel free to use it.
Thanks, jsonMe is not released at the moment so this version may have bugs. If you have any suggestions or face any bugs, please contact me
