In case anyone is ever curious, I use the F/F system to modify the karma of posts. Persons who write comments insightful to me can become friends. Persons who make shallow comments on topics I feel knowlegable on can become foes. I try to look over several prior posts before rating. I rarely make or modify ratings, only when I'm in the mood. I may have had too much time and a bad day three months ago when you seemed annoying, or been in a bleary eyed dream state when you seemed informed. Don't take it personally.
