… increased the font size on my web site by about half.
(Actually, I did it last week.)
I’m not sure I love how it looks (see for yourself here), but I think it’s a lot more readable.
I mostly made that change, along with a bunch of other tweaks, to make the site more smart phone and tablet friendly.
Given how often we see it, it’s easy to not even notice anymore how our site looks and behaves (sort of like your husband).
If your site looks/works exactly as it did three years ago, it’s probably time for a face lift.
