At the moment, this post has 4 upvotes and yet it is in the #7 place on the front page of Hacker News. How is that possible? 4 upvotes gets a post that high on the front page?

It's Saturday afternoon in the US. Not exactly the busiest time for news. I don't know how Hacker News' ranking algorithm works, but I'd imagine it's possible to incorporate information like number of clicks in addition to upvotes and comments.
There's probably an age-of-post component as well so new content has a chance to be seen.
The main part of the order is base approximately in: votes/age^2

Some of the details are part of the secret sauce, but kens did a blackbox analysis to try to guess more details. It's an old post, so many details may have changed since it was published, but I guess the main ideas remain.

If it's like the comment algo, it seems to take time into account. Brand new stuff has a short boost.
submitters karma is 25637, that probably has something to do with it.
Quite impressive karma count for only having 10 comments. A zillion story submissions of which almost all are from nautil.us though. What's going on here?
It's not as nefarious at it seems. The guy/girl just submits three or four stories a day from nautil.us / new york times/ phys.org mostly.

And over time just built up some points. Probably just shot up because of 4 upvotes at the same time.

Probably written a bot to submit all stories from a few top sites.

As others submit the same stories, the first poster has their story upvoted.

Result is that this user is credited nearly all of the upvotes from a few core sites that have content of interest to the HN audience.

Accounts with good reputation used specifically for posting links are not uncommon on any popular forum.
