This forum has long been giving good advice, which sounds like this: "Read more, write posts only when you understand that your post will be useful. If you have nothing to say, you better just keep silent."
That's true you can never be a good poster if you did not start as a good reader, once you understand and is good on the subject your post will have an impact on the discussion, every discussion leads to another but it's very important to keep the discussion within the title subject, it's not really the length but the context of the post, I have seen a short post that generates a lot of merits.
Just posting what we understand in the discussion is much better than just modifying to lengthen the post with a specific purpose, I think this need not be exaggerated we will see how the discussion leads to the main topic, and our findings provide insight into what we got I thought it would be better.
In this case, the forum is not the one for whom we are best still we can see how to mimic other people's post styles with little but meaning.
