New Activity Stream Auto-loading Mechanism
We have added a new auto-loading mechanism so that as you scroll, the streams would be pre-loaded rather than waiting when you reach the bottom of the stream.
I find the concept very interesting !
I tried on your es4.stackideas.com demo site, but it doesn't change much.
I had imagined that, rather than waiting for the user to be at the bottom of the scroll to load the rest.
Now, with this New Activity Stream Auto-loading Mechanism, the rest of the stream items would load automatically as soon as we are in the middle of the page (close to the end)
Here is my video capture on Safari :
