Top Comments are discussion forum posts we have deemed worthy of your time. Listen, we get a lot of comments, and most of the time, it's pretty forgettable stuff; but sometimes you rise to the top like butterfat in milk. We don't recommend you base your self-worth on how often we feature your comments, but we don't expressly forbid it either.
