My 30,000th yuri post.

Unlike post #9272521 (20,000) and post #8076361 (10,000), this one I blew by without realizing, and didn't choose it specifically as a milestone. Luckily, it still ended up being something good.

I have now uploaded 10.85% of the yuri on Danbooru, up from 8.3% last time. On average I'm uploading 27% of the yuri that's uploaded every day, so if everything else remains the same my total should approach 27% asymptotically. But of course, things do change.

Here's one thing that changed: hasu no tokimeki, who has for a while been a consistently strong third place in yuriposting behind me and ANON TOKYO, fell off a bit, and in the latter half of 2025, third place became more hotly contested. The most notable contenders for third place now include lavalore (who was a consistent fourth place last time), Alixiron, and Placeholder1996. You can see the full chart for 2026 below:

Regarding total post count, the top five posters haven't changed in a while (CoreMack, ANON TOKYO, Krugger, Doragonn, albert). One event of note was that ANON TOKYO reached 10,000 posts with post #10402131, making him the first person to join me in the 5-digit club. hasu no tokimeki has been climbing consistently and should reach the top five within a few months. Based on some probably-incorrect calculations that I just scribbled on a piece of paper, I expect to finally reach the milestone of having three times as many posts as ANON TOKYO in around 7 months.

In the realm of copyrights, there was a shocking upset in 2025: original (5051) was actually surpassed by Bang Dream! (6991) (and, specifically Bang Dream! It's Mygo!!!!! (6659), which was 95% of the Bang_Dream! yuri). You may have noticed that when you search yuri, Bang Dream! It's Mygo!!!!! actually comes up as a closely related tag in the sidebar, which gives me some personal insight into how Oppenheimer must have felt. The rest of the copyrights are predictable and mostly the same as last time, Honkai (Series) (mostly just Honkai: Star Rail) is third place, followed by Touhou (2447), Love Live! (2072), Zenless Zone Zero (1969), Hololive (1822), and Genshin Impact (1702). Touhou rose in the rankings primarily as a result of Alixiron's efforts, and Girls Band Cry fell off a lot, as we get further and further from season 1 with no hint of a season 2.

The most interesting question, for me, is the rise and fall of yuri posts per day, and whether this is proportionate to the overall amount of posts being uploaded to Danbooru. See the following table:

A quick glance at the chart of monthly overall posts throughout Danbooru's history confirms what we all know: Danbooru just keeps getting busier. There are spikes up and down, of course, but the trend is a gradual upward slope. More and more uploaders keep emerging, and for every Builder that has their breakdown and disappears, another 2 appear to take their place. GETs come faster and faster every year.

And yet, the percentage of daily yuri posts is going down. The daily number of yuri posts is staying flat, while the daily overall posts are going up.

The rise and fall of the average daily yuri posts now correlates poorly with the overall growth of the site, and is more a function of the current cadre of yuriposters, their number and how motivated to upload they happen to be at a given time. Most likely, the daily yuri posts will remain mostly stagnant as the site continues to grow, and the proportion of daily uploads will continue to shrink. If any of the big yuriposters drop off, or a new yuri autist emerges, the numbers will jump or plummet accordingly.

So it is with many other tags. Many copyrights are the domain of a single autist, and would die off completely if that uploader quit. Some uploaders are generalists, uploading whatever porn happens to cross their path (the snipers and scorewhores), but most of our users are autists who join the site to upload their specific niche. As users join and leave, the Danbooru's array of copyrights, fetishes, and niche interests expands and contracts. Danbooru's growth trends gradually upwards, but the growth is but the average of the expansion and collapse of the many little niches. Danbooru grows only because the many little niche bubbles that make it up are proliferating faster than they are dying off. The growth rate of each individual bubble is mostly independent of Danbooru's overall growth. There's probably some interesting analysis and research that could be done here, but I will leave that for someone else, as I am too busy uploading yuri.

I asked @grok to confirm that the above reasoning is accurate, and @grok said "kill yourself."
