To me if I compare then my knowledge is far more better than him.
Not sure about your friend, but your post history doesn't speak in your favor if it is about knowledge. There is a very big difference between Knowledge and General Understanding. What you know is just a general understanding about things, but isn't knowledge by far.
day day the post quality is getting high which attract crypto world for bounties and signature campaign.
That probably requires explanation. How is the post quality attracting crypto world for bounties or signature campaigns? Or were you trying to say something else but you did not find the correct wording for that?
I saw many jr. Member, Member and special newbie are getting disappointed due to merit system. Moderator and high rank members are giving away merit depending on post quality no doubt about that. But I think this give away of merit is not just upto the mark, many of new members will also agree with me. I'm not saying that it's worse but if this number of merit give away is increased by a little amount then it will be good for us.
The ones that are getting disappointed are probably the ones who spent all their forum time in hunting bounties or so and never cared to gain any knowledge provided to them by anyone, anywhere in the forum. Such people would obviously not be able to get through successfully and will start complaining at the end.
And, if the moderators or anyone holding the ability to Merit posts are doing it correctly then I don't see it not being up to the mark at all. The only thing that makes it only a little unfair is that many of the quality posts are missed and not Merited at all. But that is not such a big problem considering the population of the forum being too high and posts get missed when others reply after them.
