Quora got this right. The identities of those who endorse a comment is significant. There may be people who voted on the coffeescript comment who may not have direct experience on it. There is no way one can tell. Further, there may be different reasons a comment may have been voted up: 1. The comment voted up is considered relevant 2. The reader agreed with the sentiment. 3. The comment was irrelevant, but was humorous. Similarly, a comment may have been voted down because: 1. The comment was irrelevant. 2. The comment was relevant, but the reader disagreed with the point of view. 3. A polarising comment may end up with a net score of 0, but it is actually very relevant. 4. The comment was relevant, but was delivered in a brusque manner.
