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.
Yeah, there should be a way to give merit without leaving the page. Maybe clicking it multiple times moves the merit up by one each time. I disagree about only allowing one merit per post though as a person writing a very detailed and constructive guide probably deserves more merit than just someone who makes a short but informative post. Besides, it's probably easy to spot abuses when people are giving a shit load of merit out for posts that probably don't really deserve it.
This. @hilariousetc's modified suggestion of the OP should be heard and read.
Hey OP, edit your post and add this there so in case theymos would go here in the Meta and would read the topic then he can see this right away.
I'm not really annoyed that much with another window popping up when giving merits but this would be convenient if implemented.
