Hi friends. Are you finding that suddenly armed gangs are roving your street deploying chemical weapons like it's candy at a parade? You can go to Menards or a hardware store and get the 3M chemical respirators. They are in the paint section. Smalls exist but they need to be ordered. Stay safe!

"Websites that work perfectly in traditional browsers may end up broken for actual accessibility tools. The web will fragment as sites must test against a growing number of AI browser agents with different requirements." www.coryd.dev/posts/2025/a...
AI browsers are straight out of the enshittification playbook • Cory Dransfeldt
Enshittification isn't cliché, it's simply pervasive. Browsers being launched by AI companies will, undoubtedly, follow the same playbook we've seen over and over again.
