True talk,when u want to comment make sure u take your time to study the write up to make your point of recommendation or against as the case may be,for people to learn one or two things from your comment.My point is what do you understand in other peoples write ups and u want to bring out your point of reasoning for others to see base on your understanding of the article or write up,just do it articulately for others to benefit from your sense of judgement.Thanks.
