I always manually curate content because I think it's better to control who to give my "precious" votes to, and not leave it other curators to do that on my behalf. But that means spending more time reading posts on Hive, versus "outsourcing" the voting. I guess to each his own, and there's no right or wrong.
Yeah it's all based on the situation of the person. I don't have the time to do it all day and keep my voting power staying below 100% without automatic help. Not a bad situation to be in at least!
I am glad that you do and enjoy mania curation!
