Helvetica returns! And on this occasion, I am not talking about you Calum Cormack.
As I have been conducting feedback surveys on my website to select visitors for the last few days I have discovered that many do not like the Open Sans font since it is too light to read. I also felt like this from time to time and have considered the change to the slightly heavier Mac favourite font, Helvetica.
Helvetica was once the default font on OS X (soon to be macOS) but Apple dropped it for the San Francisco font in both iOS 9 and OS X 10.11. I also once used Helvetica as my default font but dropped it for the sake of cross-platform support and have switched font on my website quite a lot since then. I am hoping that Helvetica will be staying, I will be running a trial run of this for four weeks from today. If I get more positive remarks about the font on the website I will retain it.
