>why not with the much smaller matter of ordering?
I explained already, but am happy to explain again, adding a little background information. I need to keep to an absolute minimum the amount of time I spend looking for generally-interesting things to read on the internet.
Why? Because I have learned the hard way that I need to minimize the amount of time I spend doing things that are pleasurable and effortless and absolutely safe (not in the least dangerous). Consequently, if the project I am currently engaged in is to learn more about oxidized cholesterol, for example, I give myself permission to use hn.algolia.com to search HN for that phrase and read all I want. In contrast, I strictly limit the amount of time I use HN just to see if there are any interesting new stories when I don't have a definite goal for my reading.
hckrnews.com differs from the standard HN home page in that it gives me an easy way to tell when there are no headlines I haven't read already. Specifically, after reading 1 or 2 or 4 headlines I've already read, I know I've seen all the headlines below those 1 or 2 or 4 headlines, too, because the order never changes. That means that most headlines I only read once.
The order hckrnews.com or news.ycombinator.com chooses to sort the headlines is immaterial to me. What matters is that the order does not constantly change.
And that is my answer to "How do you browse Hacker News?" (the headline of the OP).
