Myeah, the first thing I saw when opening it on mobile is that the top logo is not centered and the menu is not displaying properly ("About" item single on a line with some random left margin).
Not that I care but then I was confused by the two comments here praising the design.
The logo is the one thing I didn't like but I don't want to clarify every single thing to prevent people from nitpicking and dissecting my words.
I like the spacing between paragraphs, the line-height, and the font choice. The colors chosen are pleasing as well. And the design feels simple. I even like the centered text in the footer.
I'm on my phone in bed so I can't inspect the page, but by all appearances it 16pt Arial...
Is the web in such a poor state that this is a revelation?
