Does that explain my point of view better?

I see your point, but I feel the same as the OP. I very rarely vote AM posts. I sometimes don't upvote nodes I know will have high reputation anyhow. I often upvotes posts from Monks I like, whatever it's about. BrowserUk says he upvotes all of Abigail's posts, too, so obviously who the post comes from is definetely important to many.
Everyone follows (his|her) motivations to select what to (up|down)vote for; if many people do care about whom post it is, then may be should we consider altering the way AM posts reputation work (I personnally think voting for AM posts could be "free", it would be pretty nice).
