We can, and probably will, argue endlessly what is quality, which is just a waste of time and nerves. Everyone has their own opinion, likes and dislikes anyways.

I like to get to know the people I follow and upvote regularly, to get at least some sort of personal contact. And I like to follow people who are consistent in what ever they do, ain't nobody got time to go out and search for that amazing article from a random person you have no prior contact with. And do that ten times a day.

I commented to someone else that my friends are smart, funny and talented, so when I upvote them, I upvote good stuff by default!
