"Pagination is also friction. Ever been on a forum where you wished like hell the other people responding to the thread had read all four pages of it before typing their response?"

I mostly agree with wumpus here as this relates to search results, but it is interesting that forums are brought into it because forums (generally the smaller, community type forums with long-tail discussions as opposed to reddit or even HN where discussions are generally about 24 hours max and then dropped) are the one place I absolutely love pagination.

The unfolding discussion of a particular thread tends to have a timeline in my brain that maps to the pagination of the thread. eg. Oh, subtopic XYZ, that first came up at about page 5... lemme jump over there and refresh my mind on how that came up.

Taking away pagination in forums would be a net negative for me, much like code folding is a net negative for me (I tend to have a map of the code in my mind that is impossible to keep if the code is folded in some random configuration).

Granted, this is subjective and entirely personal, so I'm not saying he's wrong (or that code folding is wrong for everyone), just that getting rid of pagination is not necessarily great for all people in all situations.
