Yeah the mixed approach works well I think. With all the tribe accounts it's impossible to do it all manually, even when you are not working 40 hours a week.
Comment voting could well be pointless unless you can clear 4/5 cents, i'd hold back on that this week and see what happens.
I try to wait until I'm 90+ or finished curating before I vote comments. However, I feel I'll be doing a lot more if I reward posts. I just feel bad for the people who don't post. I don't really comment looking for rewards often. It's hard to reward everyone or know their preferences.
