I've learned there's always a(n associative) trail of comments (sometimes from more than on thread) leading to such apparently random posts.

My understanding is that if it's in the front page, the community has decided it's interesting and a cool read, so no need to complain.

Sometimes that's true, sometimes it's just an uptick of submissions for the same url (multiple submissions count as upvotes) because it's popped up somewhere else such as reddit.
