alt Hacker NewsNo, I don't think you're unique at all. I think this all tracks and applies to more and more of the general population.
These mainstream services no longer provide what people signed up for: life updates, pictures of kids and dogs, etc. These value-add posts are becoming less frequent because of/and are being replaced by streams of posts from people _you should follow_ or content they're pretty sure will rile you up about ... whatever. Generally, the people who are still active and whose posts slip through (because it's their only outlet) are effectively monkeys slinging shit (e.g. uncles posting AI slop memes about Barack Obama's suits).
It seems like younger generations have moved on to more silo'd experiences. I don't use TikTok but it's my understanding that it's more about connecting with people who share common interests (more akin to HN or Reddit) and not as much about connecting with your high school Spanish teacher who has gone full MAGA and whose posts you don't care to see and/or who you don't want seeing your posts and trolling you in the comments. This same cohort also seems to be spending much more time in private group chats and, for the most part, the platform doesn't seem to matter; it's just a message broker.
Well, kinda yes, but not really.
Concept of SNS changed from “audience of my friends and acquaintances” to “audience of potentially anyone in the world” around 2017ish, when every feed became algo-feed. And users like it, because it is akin to “endless Reddit scrolling”, but more tailored to things you might find interesting. And posters like it too, because of potential reach and attention.
Instagram Reels has 2B+ monthly users. Even if we say 50% are bots, not active and etc., that’s still roughly 1B users. It really tracks if you stand up on a busy subway train, almost in any city, and just look around. You’ll see full screens of TikTok, IG, YouTube shorts. The younger generation’s “private group chats” aren’t some sort of replacement to endless scrolling. A good chunk of messages are links to posts in one of those platforms.
