I think about bots since I started to blog here. Sure, they help to save time when you value an author or if you're an investor or other cases, at the end I think the difference is always on "how" we use a tool, not on the tool, but I've always prefer to search/read/upvote by myself from conte to content because so I feel myself more motivated to enjoy the community and to be a part of it and I can also "adjust" the % to try to value every content in the best way. Sure, I'm sorry to miss some nice contents from authors that I love, but I think is like an off line "community" where sometime we can meet our friends to drink something together and sometime we can't ^^
As you, I have no strategy for curation rewards and I make more from my own post (that it's also a more funny, interesting thing for me) ^^
