Am I the only one that cares very little about what fonts add apart from legibility? Online I think it is mostly a distraction and I usually lock my browser to dejavu sans. I have done this since 2008. Before that I used Bitstream Vera Sans.
Whenever I turn that off I end up with a worse online experience. About one in one hundred web pages becomes better by mucking around with fonts.
I am probably just old.
Typography as an art form and communication aide is still older than you.
Like any kind of decoration (think, endless paint colors at Home Depot) it can be used effectively in the right hands. And it can also be splashed around pointlessly and even detrimentally.
I know that, which is why I have always wondered if we made it too easy. I did it myself as a kid, writing HTML 3.2 (?) by hand fiddling around with what must have been the first release of CSS. My web pages would definitely have looked better had I just stayed with arial.
They are surprisingly quite good. It would be great if they could be embedded in LibreOffice
They can definitely be embedded in a PDF you make with Libre. But to allow the other person to edit with that font, they have to own and install it. That's true of any font.
