Stacker News is too. I think they run a headless browser, load a page in HTML, then take a screenshot. I'm basically writing the image from raw pixels in Go. The "run a browser" thing is possible, but if I had to do it it would require infrastructure changes and it would leave a bad taste in my mouth. I'll think about it. In the meantime your comments have already made me switch my focus to this stupid issue and try to at least make the current previews slightly better, I don't know how you can sleep at night.
