Look, maybe you read it quickly. I understand and that is totally fine. There is tons of stuff to read and I have been where you are now a few weeks ago. Maybe you should understand that a comment like good post is a wasted comment. It doesn't make any impression, doesn't invite to reply or open a conversation. And the least thing is that it will earn an upvote from anybody. So you are wasting just your own time as well as from those reading it. If you want to show that you appreciated the post you can leave a bit more than that. See it as a lesson of advice. Others will flag this behaviour, I see it all the time.

Here, take a Tip! for taking the time to create a proper defense. No hard feelings I hope!
