No, it wouldn't. It would give you a better understanding of how other people are responding to the original post and let you double check step 2. Also, some topics can go completely off track, so if you read the latest comments, you can contribute to the conversation. For example, on this post, many people should have read some of the comments and seen that NotKasparov said that he was joking. If they were rubbed the wrong way with the original post, they could have realized their mistake and not made the post. Instead, they could appreciate his humor rather than sending hateful remarks his way.
