We are working on transitioning the default view to infinite scroll for everyone (and everywhere!).
This does require a bit of testing live on the sites. We've chosen to start this test with the tag pages on Wallpaper Abyss.
If you notice that your view is changing from paged to infinite scroll, this is why. You can always set a specific view to override this.
Let us know if you have any input on infinite scroll vs pagination. We tend to think it's nicer for users overall, but had dumb roadblocks to implementing it in the past (mostly advertiser related). Those appear to be gone!
