At any given time I have 100+ tabs open representing various lines of ongoing research. I've noticed link rot has gotten much worse over the last decade, to the point where I go through my tabs at least once a month now just to close the 404s of which there are always several. These links are rotting on the order of weeks/months, not even years. I notice it most frequently on pages that are selling something, I wonder if this is the result of some misguided SEO tactic. Might as well start linking directly to the archive.org copy of content you want to make sense in a couple years.
