Toby - I would appreciate "like" or whatever it might be called.
On the Polish forum I pushed for "beers". It was introduced two years ago ish.
Works perfect. New users can identify credibility of other users.
You can check a list who received or gave the most amount of "beers" (piwko
you can also check the most awarded posts and topics:
Every user got a number of given and received beers under his/her avatar.
It motivates users to write more valuable posts too.
I would add a full name of the user (voluntarily) below avatar as we got on the Polish foilforum:
Anonymous users got tendency to be more aggressive
- Annual Kiteforum Awards - using "likes" or "beers" you can carry out the poll among your users for example the best: video, picture, post, topic etc...
we did it on Polish forum and it was fun
