Like others I just vote for stuff I like, and usually this means I only upvote 0.001 Hive, sometimes its frustrating but i see the upvote as having two values, the monetary value, and also the value of sending the message you liked their content. Sometimes its hard to know which one is more valuable.
I am very supportive of the new changes to voting because in the end you will reward those manual curators that dont optimise the rewards, secondly those that delegated their vote because of the inefficiency of manually curating might just be brought back in, and thats got to be good for quality content.
Finally I hope we'll start seeing more upvotes on comments as these are just as valuable as posts and really add to the engagement.
