Yes it is a good idea. I delegate a good bit of my HIVE stake with no expectation of remuneration. It is delegated because I am too lazy to curate and hate to see my dolphin vote weight go to waste. Those I delegate to I know to be excellent manual curators and enjoy doing it. Mostly the folks in @theterminal. I don't remember why I delegated to that pixie thing.
Some decide on their own to auto-upvote me and that is fine. I don't really flip out about that anymore like I used to do. I am allowed to be an hypocrite now and again. I am only human.
