Personally, my takeaways from this article are to disable font smoothing. I disabled it on my MBP and I like how the default fonts are rendered now. They appear less bright and more crisper. I haven't changed these settings on my MBP since I got it, so it's likely enabled by default. The rationale behind it makes sense in low resolution cases, but to have it enabled by default on rMBP doesn't make sense to me.
However the recommendation to reduce the resolution scaling option is a no for me. The text is wayyyy too big for me and I lose out on the screen real estate.
