Just in case you are reading on a mobile device and something looks different...A friend pointed out that my space shuttle (etc.) blog background image makes the text difficult to read on mobile devices. It may depend somewhat on the device and browser (e.g., Facebook vs. Safari on iPhone), but it's different from the full-screen browser behavior, and I don't know why.So for now I have switched to a non-customized "Simple" blog template for mobile browsers.This is pretty much all white except for the text and pictures, so readability seems good. I will check into this when I have more time later this month. Maybe it's time for an iOS 7-like simplification of my blog's graphical look. Or something.
