Steve and I sat down with Jeremy Zawodny, one of Roy’s heroes, on Yahoo’s campus. MindTouch uses Yahoo! technologies extensively, we’re big fans. Specifically, we’re using YUI, CDN, Flickr API, widgets, etc…
On a personal note, I think Yahoo!, to date, has been the most adept of all the big boys in connecting and growing a Developer Network. These guys get devs and I, for one, am happy to help them evangelize their work.

All credit, as far as MindTouch is concerned, to you Chad for YDN’s success. Of course, Jeremy helps too. 😉
Hey Aaron,
Thanks for sitting down with Jeremy, and thanks for the kind words for YDN!
