alt Hacker NewsI've found that there can be a lot of randomness for what makes the front page. Not too many people read the "New" page and articles drop off it pretty quickly, so it can be hard for a niche article to attract the handful of votes it needs to appear on the front page. (Though there is a "second chance" feature which helps to ameliorate this issue.) So there's a lot of randomness to what makes it onto the front page.
For instance I submitted an article three times (spaced a year apart). The first two times the article got no upvotes. The third time it got 600+ and hit the top of the front page. It's just a matter of who happens to be looking at the New page at the time.
I've found that there is a snowball effect too
If someone has less votes and its still something I find interesting, I am more critic of the whole situation to upvote
But if someone already has 400 upvotes and is on the top of the site, I will look more into it with ("woah a lot of people upvoted, lets see why" and then read the comments and some of the comments are really brilliant that it becomes the reason why I upvote the post itself too
I am sure that hackernews doesnt really recommend it but I do feel like its something that I do subconsciously that I have observed and wanted to share. It does feel like random stuff but still in a way which still makes sense for the whole ethos of hackernews.
