Gee, I wish I'd of thought of that...
Sezwho -- very cool. Just signed up. I don't like the "rating" -- cause I'm a fan of "recognition" -- but I've already signed up and can't wait to see how this works out. I'm also not sure how the weighting they discuss will play out in the long term:
Q: How is the SezWho "Star Power" scores calculated?
A: The SezWho scoring algorithm is a proprietary page-rank-like recursive algorithm based on reputation score of rater and commenter, their frequency of participation, time of interaction, consistency of participation and topic of discussion.
-- we gamed that fairly thoroughly and came out with a different conclusion. You never know, they might actually be targeting the cult of personality we were trying to avoid. And that could be the right thing to do.
In any event, I can't find any way to ask them for a Community Server plugin -- but I'm still looking.
