Yes - and all the people the author remembers with nostalgia are probably on Twitter now, doing more or less the same thing but with worse quality overall. Twitter gets a bad rap because of the hive mind (and it deserves every bit of that reputation), but there are tons of just normal people on there talking about their lives. In a way, Twitter made blogging much more accessible - most people couldn't sit down and write a 500-1000 word post, even one or two a year, but they can tweet every detail about their day, their projects, what they're thinking about and so on.
Of course, it's not the same as a blog. I think the length "requirement" of a blog made it so only people with the time, dedication and skills (or lack of self-awareness) would keep them going, so if you were reading an established blog a bit of selection bias was at play. On Twitter you can tweet garbage day in day out and still be on the platform for years. Heck, you'd probably gain a significant following.
I might be coming off as a Twitter fan or something but just to be clear: the site is cancer. It's impossible to stay on for longer than a year and not have your brain melt off by how it works, and they're becoming more and more closed and restrictive by the day. It's a shame because there's clearly something about the site that interests a mass audience, but I wish there was a service that was like Twitter but better. I know Mastodon exists but outside specific niche audiences it's never gained traction, but I hope it does take off eventually.
Maybe the same applies to Facebook/Instagram/Other major social media provider as well, but I don't have any experience with platforms outside Twitter and Reddit so I couldn't say.
Edit to expand on something: I mentioned that Twitter is interesting to mass audiences, and that's actually more important than you'd think. Speaking personally, before I went on twitter, I don't think I'd ever consistently read content posted by women. It's a natural result of being in a male-dominated industry and following male-dominated interests. On Twitter, though, because there were so many people of all walks of life I quickly followed a lot of interesting women who posted great content: women who were activists, historians, academics, homemakers and so on. That really was why I stuck around for so long on Twitter despite how awful the site is, and why I think any serious contender has to appeal to the normies, so to speak.
