As of right now I don't have to worry to much about over paying a post, (glad of that). There are a lot of reasons why I vote, mostly content, some for people, and then for maybe a slight reward advantage, but mostly for people and their content.
I know some people still have issues with some auto voters but I think that is going by the way-side. People are beginning to understand and are trying to be more realistic in their views on voting. It takes time to find content to vote on. Some days it takes a lot of time to find content to vote on, and that is just for me who only needs to find 20 pieces of content or 20 people to vote on a day. I can not for the life of me imagine having to find literally 100's of things to vote on for some accounts just so they don't appear to be maximizers. Auto Voters help in that regard.
One day I will need to use an Auto Voter, but for now it is nice to be able to pick and choose the topics/people I like. The peakd list function helps a lot in that regard, so I suppose I am a manual auto-voter because I can always go to one of my list and toss a few votes on people I have enjoyed in the past and hope stay around.
My brother was talking about this for curangel, which has a dollar limit it will vote to before rejecting the submission. The problem is, the unrewarded posts are often terrible - finding decent content is hard and will only get harder. Finding 100 pieces a day is near impossible.
That is why I try to keep building and adding to my various list. A lot of the people I add just disappear. I follow a few that re-blog some new users, like steevc, edprivit, and angryman along with a few others, and I follow a few contest that attract new users because they are simple and uncomplicated. Scrolling through the new user list is a nightmare.
