So, forums "pays". I agree with you. But SM doesn´t, thats the reality. And I see SM crushing forums, so may be we should learn from them. I´ve never seen people complaining because FB, TW, doesnt give them badges, ranks, titles... and that´s because people doesn´t care about them. They want a clean, modern interface. Filling their screens with medals, badges looks really old and annoying. They dont want to see badges, or how many posts, or likes, has a member every time they read a comment.
Maybe Im wrong, but that´s my opinion, we all are trying to learn here and be better admins for the good of ours comunities so I like to read yours opinions even if we dont agree.
