You write something worth upvoting and I upvote it.

I should have been more clear. What I meant is how the posts are sorted on the main page, because they are clearly not sorted by just upvotes (e.g., post A with 100 upvotes may be No. 1 post, while post B with 1500 upvotes may only be No. 5).

It is like many of the pages on sites like Reddit and danbooru where the ranking function is like

   votes / f(time since submission)

where f increases monotonically. A submission that was made ten minutes ago needs fewer votes to be at the #1 slot than one that was made ten hours ago.
