The irony here is that modern social algorithms actively conceal these for exactly the same reason. Social feeds want to show you a steady stream of content that you are likely to engage with. They are incentivized to frame content as literally timeless and impose a continuous, never-ending present on the user, since they don't want recency to get in the way of engagement. But the time-context in which a piece of media was produced is a fairly important detail in critically evaluating it and situating it in an actual, human conversation.

Did this piece of writing with common AI smells get posted before or after 2021? Did the author write this piece about someone they admire and aspire to before or after the murders became public knowledge? What was the expert concensus on the topic when the author wrote about it? What meaning did this slang have back then?

What technologies were commonplace? He said he needs help with something I'm an expert in -- can I help him, or was it over a decade ago?

What was happening culturally when this was written? What was the weather like? Did this collection of posts with a dour tone get posted during a global pandemic when mostly everyone was self-isolating? Did he write this post about his loved one before or after her death?

I mean hopefully I don't need to sell you on why this information is useful and actually antithetical to addictive, low nuance, engagement-driven social media. We need more media literacy, not less, and de-emphasizing critical details like this seems problematic

I do sympathize with the challenge and know that there aren't really easy answers here, and every possible change is likely to ruffle someone's feathers, but I have a feeling there is another way to achieve what you're after.
