Karma is back? That didn't end well the last time they implemented it (remember the + Vs - feedback wars going on?). Kind of fun for awhile but too many people took it all to serious and the grief wasn't worth the value in my opinion. But I will take my 81 karma points in the spirit they were given. 
Don't yet see where you give karma out in new posts? Perhaps this is just a site hick-up to go along with the very slow response time we are getting over the last week or so?
