From Michael Bolin’s post on the GData APIs blog:
For those of you who have been trying to build client-side GData mashups but have been thwarted by the same-origin policy, we have some good news for you: you can now get public Base, Blogger, and Calendar feeds as JSON! This means that you can start displaying GData in your web page with a little JavaScript.
This means you can take any feed from the new version of Blogger, add alt=json-in-script and callback query parameters, and get a JSON representation of the feed that you can manipulate with JavaScript on any web page.
If you hack up something cool, post about it on the discussion group or link to this post so we’ll see it in the backlinks. Extra points if you share it as a widget with our new Add to Blogger API.
