No, college is more like this: You see somebody, "Jd", (except let's call him "Harvard") who already got a lot of upmods, and you attach yourself to him by replying (except, let's say "applying") and bang now my comment is closer to the top of the page.

More people read it, leading to an extra opportunity to gain Karma. Of course, if I don't stay "on topic" (let's say "go to class") people will notice and downmod me (let's say "flunk me"). Staying "on topic" leads to a dull uniformity.
