i think that dead internet is another form of enshitification that’s more common on platforms that are backed by significant financing. eg reddit, facebook, bluesky, etc.
anecdotally: your experience gets richer on social media if you avoid platforms that describe itself as “general interest” or with investors behind it since both have an interest in trying to attract as many people as possible rather than letting people’s interest organically lead them to your platform; lemmy was a great example of this before the reddit enshitification.
latine originates in south america and does the same thing that latinx does; but doesn’t carry the divisiveness of latinx because of that origin. (ie latinx is usually fine with americans who are latino; but latinos who aren’t american, or are newly american, sometimes don’t like it because it feels like cultural appropriation to anglicize a clearly spanish word that identifies them).
also: latino and latina does not include people who don’t identify as either and is also cumbersome in english when you want to use inclusive language; latine gets rid of all of that.
and i’m also old and decrepit; i still keep defaulting to latino too.
