If hacker news did not have a voting system/flagging system/banning system it would just be a giant cesspool of links and comments submitted by bots.

If something that sounds interesting was published in Nature/Science around 2000, I will usually just skip it. I already know the methods section will be crap and I will be unable to figure out what process generated the data (at least in the case of biomed). When I needed to dig through that stuff and try to make sense of what was going on in detail, that was an awful nightmare. And that was an editorial policy... now they at least let authors put the required info into supplements.
I think that was the era of "peak peer review", the idea has been losing clout ever since (mostly due to the internet).
I love the example of the New England Journal of Medicine finding that paying $5 was worse than not paying, as potential reviewers found it insulting.
As to other activities, yes, I think companies behind journals typically pay people to do administrative functions for the journal, and the editor may or may not be paid (for Nature, I believe the editor is paid). However, it is possible to replicate the traditional review structure in a completely free OA journal with volunteered resources; in computer graphics, I think JCGT does this: http://jcgt.org/about.html
