Don't worry, they're killing that too, with infiniscroll!
Seriously, that's another thing I hate about infiniscroll: if I come to a giant list where I know I've looked at the top 10% of, it makes it impossible to jump down approximately 10%, or otherwise to a region I know I haven't explored.
Edit: And, of course, if you do want to go n% down, there's no choice but to page down, wait, page down, wait, page down ...
The #1 thing I hate about infiniscroll (and I actually kinda like it when I'm vegetating and pouring crappy content directly into my eyes) is that clicking on something and then hitting back almost always takes you back to the top of the list; at which point I bounce out and never return.
However, that one I blame the browsers for. I distinctly remember the back button working differently, where it would reliably take you to the exact state of the previous page, just as if you had opened the current link a new tab and closed it, but it changed at some point, and most sites do something that destroys the state when you back into them as well.
