I think it is a good tool to have, I just think its usage will be somewhat limited. Perhaps it would make sense in the future to partially base how much a post is worth on factors other than purely votes. Some possibilities include number of comments, number of comments receiving upvotes, number of views, etc. I think the primary factor should be votes but this could be modified up or down on a percentage basis based on some of these other things. or maybe some mechanism that limited vote values on some scale...i.e. the first 100 votes are worth 100% of their normal value, the next 100 are worth 75%, etc. These are just a few random ideas and there are lots of possibilities. I think the situation will gradually improve over time.

There's no such thing as an "objective" upvoter, at least not in terms of the value of the content. The value of any piece of content to any given person is purely subjective. If people are worried more about whether or not their vote earns them (or someone else) more money than whether or not they like the post, I think that is counterproductive. People should be upvoting what they like if we want a consensus of the best content in trending/hot. If people really don't like your content, it shouldn't be getting upvotes just because it is there, regardless of how much work was put into it.

I wouldn't necessarily be opposed to blockchain enforced daily or per post limits but i think these would have to be limited only at the extremes. I also think having to provide a reason for a downvote might be beneficial though I'm not sure exactly how that would look.
