Infinite scrolling == infinite memory usage.
Whenever I go to some forum that's heavy on pictures and videos that has infinite scrolling, and I'm looking far down the page for something or other, eventually my browser slows to a crawl, or the browser's resource-hungry JS engine crashes, and that's the end of the scrolling.
Certain sites I patronize that have the stupid infinite scrolling also have the classic &page= HTTP GET mechanism. On those sites, every once in a while, I reload the entire page with a &page= corresponding to roughly where I am in the infinite scrolling, just to reset it and free up some memory.
It's not the UI paradigm that bothers me, it's the resource usage insanity.
