If it’s worth saying, but not worth its own post, here's a place to put it.
If you are new to LessWrong, here's the place to introduce yourself. Personal stories, anecdotes, or just general comments on how you found us and what you hope to get from the site and community are invited. This is also the place to discuss feature requests and other ideas you have for the site, if you don't want to write a full top-level post.
If you're new to the community, you can start reading the Highlights from the Sequences, a collection of posts about the core ideas of LessWrong.
If you want to explore the community more, I recommend reading the Library, checking recent Curated posts, seeing if there are any meetups in your area, and checking out the Getting Started section of the LessWrong FAQ. If you want to orient to the content on the site, you can also check out the Concepts section.
The Open Thread tag is here. The Open Thread sequence is here.
I am delighted that you chimed in here; these are pleasingly composed and increase my desire to read the relevant sequences. Your post makes me feel like I meaningfully contributed to the improvement of these sequences by merely asking a potentially dumb question in public, which is the internet at its very best.
Artistically, I think the top (fox face) image for lotteries cropped for its bottom 2/3 would be slightly preferable to the other, and the bottom (monochrome white/blue) for geometric makes a nicer banner in the aspect ratio that they're shown as.
