This page has PNGs that need serious optimization. On my monitor, those 2 Cloudflare page screenshots are ~2000x1000 PNGs that weigh 700k each. They occupy about 850x500 "px" on my monitor. (The logo and author pic are likewise, ~300x300 PNGs downscaled to ~40x40.) Serving lossy images at such high resolutions sorta makes sense, but with PNGs they kill page load times. These images could probably get away with a lossy format and much lower resolution, and the page would be less than half the size it is now.
For a small mostly-text blog post? Wtf are you talking about? That’s absurd.
