I agree with you. I hope karma is not implemented on Lemmy. The up/downvote system is fine the way it is now. I will say also coins and awards. I don’t really think those are necessary. I’m aware that was something characteristic to reddit (correct me if I’m wrong) but I prefer all that to not come back.
Really specific issues are more often than not only found in reddit, and that’s not even all, for me at least; a lot of those answers in reddit are short and to the point. Sometimes you search for the solution of a problem and find posts on websites filled with irrelevant information that you don’t really have the time/patience to read. . .
