Ignore Lists are like mute buttons. I prefer to see everything and use my scroll wheel.
I get this point in theory.
In practice, time is opportunity cost. I want to maximize my funtime here, and part of that involves curating my experience, much like I do with muting/blocking accounts on Twitter (where I fucked off to, during my absence here)
There are some people I will never agree with, and don't care to read their opinions/content, because it literally is a waste of my time, and a net-negative in my life, so I prefer to curate my experience to optimize time.
I agree with Bob, I have very few on my ignore list, but the ones I have are just time thieves as I see it.
