Bitcointalk is a broad community where bitcoin technologies and informations are been discussed, so what I observed in Bitcointalk is that for me to go further I have to read what others has written properly and make my contributions to where I understand a discussion.
It is important to read before you try to correct other people's posts and the basis of the forum is a discussion where everyone needs knowledge to continue an interesting discussion. When you understand what is discussed, it will give birth to knowledge that can be shared with others.
The favorite mistake that is often ignored is that they only read the title of topic without reading the contents of the post on the first page. Sometimes one or two previous replies are constructive enough, so there's no need to have a third reply for the same thing.
