I have been a memeber here for many years. And have made innumerable high quality posts educating and helping my fellow bitcointalk members but I have yet to ever be noticed and recognised for my efforts. I only noticed the merit system TODAY and I cant believe I dont have any!
Even if you post a quality one , when a user do not want you give a merit it is only a normal one because giving merits to someone depends in the users of this forum if they will give you or not. There are post that are that quality but some users give them the merits its because there is no definite users to give merits. And even the post you made is helpful but they do not want to give merits in your posts you cannot do anything about it.
