Looking at the biggest "talkers" on goEMAW (posters who were involved in more than 100 quotes) :
The posters on the left hand side had more posts of theirs quoted than they quoted of others, and the posters on the right had the opposite.
Perhaps one way to interpret this is that the deep red folks are the conversation starters/drivers. But its not necessarily only positive, perhaps to too much of an extent, they don't reply much to others. They could be contrarians looking mainly for reactions/fights and don't bother replying.
The people in the deep green are conversation killers/enders. Perhaps they need the final word or maybe more charitably they have a irrefutable position. It's not necessarily negative, they could simply be the ones who neatly conclude an issue so it doesn't drag on and on, and they drive conversation by replying (maybe even mercy replies to posters who don't get paid attention to).
The middle people (right around 0) are the balanced posters who quote and are quoted in equal amounts. They are momentum keepers and crucial to the health of a dynamic BBS.
