I actually think the 100% vote keeps me very honest. I have read articles of friends that I did not like so I did not vote. Well, I will also miss to read some good articles, but I only got so much time in the day :D. It would be great if Steemit offered more than just the feed or "manual browsing". If I am off for a day it is hard to keep up.
I am actually thinking about keeping my vote at 100% and only upvote posts I read and liked. On long interesting conversations (mostly political) I tend to upvote one of the replies. HF19 is also great to promote discussion in comments, imo. Of course I not only upvote convos on my posts, that would be baiting as well ;).
Yeah, I would love to have some extra filters in my Home feed. Simply being able to filter on tag would already be a big help.
I like your way of looking at it. I don't think I'd have the discipline for it though, i want to upvote too much :-)
