That is what is written in the post itself.. Sometimes, I was even suggested to do that.

I do not totally agree with that. As, I think having a little value to the post is better than having nothing. I prefer writing something that I can go back and re-read it and see that there was an idea behind the post itself. Even, if this post is not my best. But, I think it holds a little value, compared to writing something that I might read again and think that it holds no value.
