Once I was researching logical properties, and I took an article page from a magazine website, and I popped it through Google Translate and had a friend of mine who read Arabic check it out. They said it was fine. About what they expected from a translated site. Then I replaced all the CSS on the page with logical property values and again translated it, and they said it was, surprisingly to them, much better. There were things that felt/read/looked better that they didn’t expect, like the header/navigation/logo aligning itself in a way that felt better to them. So it it the biggest deal in the world? Maybe not, but it fixes little things and it’s a net gain, so that’s enough for me.

I do use -inline and -block, as a convenient way of setting two sides in one rule without respecifying the other two sides. Beyond that I’m going to need some evidence.
