I don't even look at how much merit i have or don't have. I have never posted to simply gain rank either and never will. If you post only to get merit or further your rank than you need to re-evaluate yourself because it's a waste of your time. Why would you roll like that in the 1st place? The rank has no difference, newbie can still post and read everything i can and jr member (which you don't even need merit or anything much to attain) can enter most bounty campaigns so what is the big deal with merit? Business as usual if you ask me. I use bitcointalk to gain trading knowledge and learn about new coins and events in the crypto world. Why is it that humans always form social hierarchies with ranks and levels anyhow, and than the masses want to conform to these systems?
There are always two sides to a story; while
you may not need the merit to rank up, others do. Because the information or data gotten from the higher ranks ought to be authoritative in their assertions.
Else, before now, if as a newbie you depend on ranks to guide your investment choices and trading strategies, you might be in for a long-term loss:
"...I use bitcointalk to gain trading knowledge and learn about new coins and events in the crypto world."
But the ranking system can help sift through the pile of junk comments and remarks, and while ranking up is a compensation, it does well for the future newbies, crypto stakeholders and the forum for credibility.
But you are right, hierarchy is always a problem as long as people want to beat the system, but a system without one is chaotic and disorderly - and that's human nature by default.
