I feel that posters should get recognition for text of theirs that is quoted by someone else. After all, it did spawn further discussion whether or not it was "liked" or hated. Liking posts is pretty subjective while quoting is more direct.
The 3 like measurement already takes into account not all users will/can give likes. If it was based on quoting the bar would be much higher... More like 200 times or something. Not only that people can quote you because they are responding to idiotic questions or something... So not sure it would be a good measurement at any level.
That makes sense. Not sure that the coding effort would be worth while to anyone except me, but a trophy level or stats page might be interesting. I didn't see anywhere where you could see the most quoted or arguably influential poster on the forum.
