The post HF19 environment definitely invites us to become good at "resource management," as far as using our voting power goes... and yes, experimentation is important there.
Of course, newcomers don't get a slider till they have... what? 500SP? So they may run out of gas pretty fast, unless they understand that their ability to upvote is limited...
Some of the other apps have a slider right away. But newcomers probably won't know about those apps, either. I can see the newcomer mob mentality working on the trending page - big time. But as people understand Steemit better, I'd hope for more balanced outcomes. I hope it doesn't make us all more stingy with our votes, however we distribute them.
