Absolutely. You used to be able to reliably go to the reddit comments section for more information/context, clarifications/corrections/alternative takes, sources/citations, etc. on pretty much any post. "The real TIL/joke/story is in the comments" and all that.
Nowadays the reddit comments section is all jokes (not even good ones), reaction gifs (not even relevant ones), and non sequiturs. I'm unclear what percentage is bots and what is oblivious people with nothing useful to add but a compulsion to contribute anyway.
I keep visiting the reddit comments section anyway out of habit, and nearly every time I walk away feeling disappointed and a little dirty. Fortunately Lemmy's comments are more like the old days when you at least felt like you were conversing with a human (and a literate one at that). Unfortunately outside of a few niche topics, Lemmy is severely lacking in subject matter experts, so there isn't anywhere near the same level of additional context and fact-checking on most posts that used to exist on reddit. I don't know if this is a demographics problem or a "we're under the critical mass threshold" problem; I assume it's both.
Not a paleontologist, but these renditions seem shockingly consistent for a dinosaur. T-Rex for example went from full upright to balanced to covered in feathers in half this timeframe. And let's not even talk about poor iguanodon...
