I'll say this: when you log into one of the incumbent social networks like IG/X/SnapChat/Facebook and you see a post that you don't care at all to see, why are you seeing that? It's because they want you to see it. They think that this post with this content and these reactions has the highest chance of making you engage with it and see more ads. The best example of this is navigating reddit.com vs old.reddit.com. The fancier reddit.com always recommends me stuff that I don't really care about but end up clicking through on because I am weak and they know I am weak. old.reddit.com is closer to the old internet that I enjoy: I check in on topics/subreddits I'm interested in and then when nothing is new or interesting, I do other things.
Arguably, building a platform that's less addictive is foolish and leaving money on the table. But as someone who had to quit IG for 2 years (though I'm back on it now) I really don't want to sell people a digital drug addiction. I see YouTube videos which are basically just rage bait and I'm like, why would I want to support a world where acting in bad faith is the hallmark of a lucrative career?
To answer your question more directly, the internet has given me a lot. One of the reasons I'm so into soccer/football is because following the /r/soccer subreddit taught me about the sport and after browsing on/off for a couple of years I can tell you all the big storylines. I never in a million years would've been a football fan if it weren't for the subreddit. I've picked up hobbies like shuffling to house music by following various shufflers on IG. I keep in touch with friends from middle school who, if I grew up in earlier decades, I would've lost contact with a long, long time ago. All because of social media.
The internet can be a great place when the platforms themselves allow us to control our attention. I'm optimistic about PIECES and the other platforms we're building. I want people to feel connected to other people. Is there anything more important than that?
