When you comment on a post, do you read the other comments first, or do you comment and then read what others had to say?
Sometimes the post isn't clearly stated or there might be varying interpretations. If that's the case, I might read the responses first. Generally, I jump right end and tell them what I'm thinking. Sometimes with the result of throwing egg in my face.
I do some of both, Sometimes it's because it's a long post and there already could be one or more comments that are the same.
Other times it's because I don't really understand the question so I'll read a few to find out what's going on.
Many times though, I just comment blindly.
