Yes, I was excited when I saw JSON Resume on HN this summer. I wasn't able to fit it in with all of the other things I was working on, but I think it makes sense, especially as more people use it. JSON Resume has more in their standard than Creddle currently supports so there's work to be done too (:
Awesome! We are just doing up a blog post now for http://represent.io who now supports JSON Resume as an export type.
Let me know if and when you do import/export support and we will do a blog post also and list you on the homepage.
