2022/03/03: I started using Simple.css, by Kev Quirk. It's... indeed remarkably simple to use. I also never got around to finish auto-generating the "little tiles" layout, plus many articles don't have images anyway. (More details here!)
2021/10/22: We have an RSS feed now!
2020/09/06: here comes an entirely new layout, with little tiles.
2018/08/05: clickable images with a gallery! (... which is nice & mobile-friendly.) They only work within the posts, though.
