Sorry to hear that. I write/preview on desktop first and typically like the legibility that comes from the line spacing, etc.
What would you change to make this a better desktop experience for you? Less of the full-width photos? Text that spans wider, or just lest line spacing?
If it was me I'd delete both large photos (neither relevant to article) and zoom out to 80%.
I'm not sure what PC you're using but full-width is not nearly as egregious as full-height. On my 20" 4:3, the first photo is almost exactly 100% height, second is perhaps 120% height.
Are people surprised by this stuff? I can't be just an old coot shaking my fist at the kids on my yard. Compare the blog to HN, side by side. Or Wikipedia. Or Washington Post. Look at the content density side by side.
