I see dynamic loading at this URL with both chromium, opera, firefox (iceweasel). Try refreshing with Ctrl+F5.

Are you talking about the side-bar 'info' tab? I couldn't find anything else which is called 'page info' in opera. If so, it shouldn't show any changes.

Google search doesn't this kind of infinite scrolling, there is just a page switch. Almst the same behavior is when you just click on the forward/backward links in hg log (I mean +-N). The links not always work as expected for edited history and stripped csets (yet), but otherwise they seem ok if you want this. Google images use some kind of infinite scrolling on the other hand, and it's quite similar in behavior to mine one (not exactly).

What would you suggest here? I'm almost certain that changing the numbers will confuse (much?) more.
