In a previous post, I wrote about using ajax to load list of content to eliminate the need for next/back buttons. I was thrilled to see that something like that is used on Google’s RSS reader. As soon as you scroll down a feeds previous posts, it will begin loading in more. I’m sure they probably had that functionality for a while, but I just switched to using their reader for my feeds and discovered that. I’m a huge fan of the innovation coming from Google so it was a joy for me to see that I was thinking along the same lines as the dev team for Reader.
