I was going to ask for a feature that locks the question offset once you browsed into question pages (page 2, page 3, etc) but I see that this has already raised before, see Suggestion to make newest questions browse more useful and Option to keep pagination fixed as you are browsing
So if SO is (one of? The only) site affected by such high question volumes, how do you browse new questions?
I mean, yes, I can use tags and only browse questions with my tags, but what about the benefit of seeing questions outside my usual areas of interest?
(I guess that reloading the main page, which will show pages of unseen questions if I take long enough to read them all, is only slightly different from browsing older and older questions... :-) )
