I am voting manually for everything but I haven't been around that long so I am still trying to spend as much time as I can around and find other people like me. It is very easy to miss an article for someone you follow though, and if you believe in their capability to write good posts I find it quite alright to set an outoupvote bot for them. There are people from all over the world and timezones very easily mess this up. I follow people from everywhere and miss quite a bit and go to their walls to check. But still bots aren't all bad.
