>Why break conversations into awkward and arbitrary pages, where you have to constantly find the Next Page button? We've replaced all that with the power of just-in-time loading. Want to read more? Just keep scrolling down.

While I like this for viewing lists of threads, I'm not sure it's a problem that needs solving within threads. Maybe it's just a symptom of my confused mind, but I actually like reading a few pages of a really long discussion, then coming back later to read more. Here I come back to the top and hell if I'm going to try to remember where I was.

I no more think paging needs to go away than I think chapters in books need to go away. Or pages in books, obviously.
