For some people complaining about the state of the Internet seems to be an end in itself. We might have lost some hacker/open culture along the way, but there are still good bloggers, there are still good forums, there are even good Facebook groups for hobbies that simply weren't on the Internet back then.
You have to look for them just like you would have to look for a good IRC/Forum/Blog back then. The bar of entry is discoverability and what your interests are. I highly doubt that finding dedicated beekeeping community is harder now than it was 20 years ago...
Hacker culture is alive and well, but you aren't going to find it on Twitter. They even call HN "the orange site". Because orange = bad, got it? Unless you're code golfing, there's simply no way to "hack" or talk about anything worthwhile in 140 characters anyway.
