But still - I'm careful of my voting power and I don't want to upvote "all" of my friend's posts in many cases. They might post on two topics and I only have interest in one. Plus you never know until you look what is in the post.
What kind of criteria do they have?
There's none. It's just an auto trust. So it may not be for you.
Yes, I think I am too ocd for that :)
