2) Are you making enough posts: The number of posts you made so far are also very less. The more posts you make, more are the chances of getting noticed.
That is terrible advice. Spend 10x more time reading and learning from the forum than you do posting. That way you stand a chance to gain some knowledge and then make a valuable contribution when you do post. Over-posting just to increase activity was the very problem the merit system was brought in to solve. Making more posts if you have nothing to add to the conversation will certainly get you noticed, but only as a spammer.
But since people believe more posts will increase their chance on getting merrited, isn't this proof that this system is not working? I believe it is.
