How has reddit changed over the years?

I remember being active on reddit maybe from 2008-2012? Then came work and kids. It feels so much different now but I can't actually remember how it was. It's definitely a lot more broadly catered than it was before, but the niches feel more vacant. Like there'll be 15-20k members of a niche interest subreddit but only 10-40 posts that barely interact with one another on threads that happen every several days. Then the big threads from big communities have so many comments it feels like it would be a waste of time to post anything at all cause how does it not just get buried in most cases. Makes sense that people are probably oversubscribed and on more media platforms than before, and they probably only make it through the first so many hot threads or whatever before moving on. Also the internet just generally feels more shallow and uninviting and simultaneously overwhelming, so I imagine that has something to do with it. I dunno. Feels weird but i don't even know/remember why it feels that way lol. Would love any insights.
