11-year-old posts are fine. It’s not like pizza-cooking techniques become obsolete; if there’s old wisdom I still want it.
It’s just, you know, better not to quote shitposts, you know?
This thing where search engines only want new results is actually quite bad. I was looking for advice on exactly how to physically arrange the wiring and connections for some batteries in parallel. SearXNG gave me great results that were really helpful from electricians posting on old forums of varying age. DDG and Google only gave me bullshit SEO sites. But they were new!
That post on mastodon claiming that it strictly came from a reddit post could purely be coincidental. If you Google "how common is glue in food," you'll find a ton of links talking about commercials using stuff other than food in food commercials/ads to make the food/drink look more "vivid/full/whatever."
Don't browse mastadon. I came to this conclusion myself after finding the reddit post in question. The answer from Google wouldn't pass a plagiarism test, the wording was nearly identical.
