There's a lot of stuff that changed:
- Past: fewer people online, mostly curious and quirky ones; now: everyone's online
- Past: fewer creators; now: everyone's a creator with an FB/Instagram
- Past: doing stuff for fun; now: doing stuff for $$$ (maybe not all but definitely lots). Thousands of thousands of YouTubers. We're flooded with content every day.
- With so much content to consume, the desire for creation vanishes.
- I also feel like the societies getting more well-off kills the innovation. When I was a student I couldn't really afford many things, so I had to be creative to get around that. Now you just pay a few bucks to some internet giant and all your problems are solved.
- I feel like facebookization killed many online communities. What used to be an independent phpbb board with a logical structure, room for customization and some tools for admins to manage it, became an FB group that is impossible to navigate and manage sensibly, with posts ordered by an algorithm, and which spams me with notifications at the least convenient times.
- Other downside of power grab by FB: I hate when all my real-life friends get spammed by every little post on every shitty FB group I make. This totally killed the anonymity of the net and separation between various communities.
- Societal radicalization means there's more trolls and aggressive people than before, which makes me less keen to engage in discussions with strangers (apart from HN, one of few places that keeps the level).
- I used to read news on the internet to save time (among other reasons). Now with all the heavy ads-bloated, video-bloated, SEO-optimized gibberish content split in 15-pages slideshow, and clickbaity headlines, I think it might be actually more informative and time efficient to read and oldschool newspaper or watch evening news.
- Having said that, maybe it's just the old guard getting old, and having less time to explore -- getting busy with work, families etc.? On Reddit, there are lots of very weird subcommunities I'd never think of. My younger brother still plays Deluxe Ski Jump like it's early 2000s, and hangs out with the other guys who do the same.
