1. The process of sending merit seems a bit annoying. You've to go through another web-page and select number of merit to be sent and then send it. IMO, it'd be better if it could be sent just by clicking "+Merit" button right within the thread.
2. It'd be much better if you guys allow only one merit by the merit-sender per post. This will reduce fake-merit-exchange or fake-merit-giving. There're people sending tens of their merits to a single post which clearly seems like something fishy.
It is really true that the purpose for which merit system was introduced is not being fulfilled completely . It seems like the users always find some way or another to benefit themselves . Many of the users are giving merits to their other accounts and just trading it to upgrade their accounts and rank .
I have seen many users giving 20-30 merits to one some accounts for just one post .
Also the new window opened by merit is not a very good interface , so making it "only one " merit will be a better option .
