First of all congratulations Alex!
I also feel the same way about reputation systems, whether it's this score or the user authority. Of course, I'm nowhere near your numbers.
But they do matter for readers sometimes. And having a rep of 70+ draws attention positively. As does having a -5 or a 32, but in different ways. If I were to read the comments of steem-ua on my posts, they often draw attention too, but in a negative way.
