What seems like a zillion years ago, font discussion was right up there. WEB fonts, G fonts, embedding and more.
Personally made the choice back in 1996 to stick with "system safe" fonts and when CSS came out was glad I did. Worked out well for myself and clients over the years.
PERSONALLY, however, things began to change. I could not SEE as well. Other factors (such as stupid shades/colors/fonts) made reading even more difficult. I had to make a decision if the web was to remain useful FOR ME.
In my case? My computer/device is fixed in HIGH CONTRAST. In other words ignore all colors from websites: black page, white text (ie. 1980's CRT screens), yellow for unvisited, green for visited, FIXED font (Georgia in my case for serif, Calibri for san-serif, and Courier for monospace) and pixel/point size FIXED at 16, denying page font suggestions.
FOR ME this produced a VERY PLEASING and USEFUL experience on the web. It also surprised me a bit in that nearly 100% of all websites are usable! No weird margins, lengthy times to download a font...
My question to the WW gang is are you actively future-proofing your sites for ACCESSIBILITY? High Contrast is one of those factors for the vision impaired. Do you test for this with your layouts? Most users are not as savvy on how to take control for themselves, but they DO know that there's a function that can make things better and most system OS can provide that.
Do you take that into account when creating your product?
APPARENTLY some do---for that my eternal thanks!
Interested in your thoughts ... after all, we grow older day by day!
