I could not agree more! It has unfortunately become a trend to use light gray on a white background for web sites. This is a horrific design choice undoubtedly chosen by people under age 50 who still have excellent visual acuity. Not fair for those of us who are older!
Guys, if it is a big deal, you can "invert colors" on an iphone. Additionally, we will have an app out in a few weeks with a darker color scheme. On desktop, you can turn down the brightness on your screen and that should help.
I'm not moaning as such, I don't mind the light screen, I just prefer a darker screen and it is often just a case of selecting a different "skin" on a forum. It is no big deal if it's not just a case of ticking a few boxes down your end
