It is hard enough that I have stopped trying. Just not as motivated that is all. If you are super duper great poster with above average knowledge you won't have a problem. But if you are just average, you will put up a post that is useful and with new information and people recognise it as such, but don't give merit. You can also be quite sure that if you have expressed a political view, people of the opposite view will not merit you. Or even ones that share your view but are afraid to appear biased LOL. It is very possible for excellent posters, for average not as much.
