Indeed. I was trying to sell a loft bed a couple years ago and Craigslist is essentially dead for that sort of thing now, killed by Facebook (I deleted my account in 2021 and I have to say that eschewing that corner of the internet has been a net positive for my mental health). The only replies I got were obvious scams (“I love this! I’ll pay you $100 more than you’re asking for it!”)

Some forums are still alive, although not with the vigor that they had twenty years ago (talkbass.com is one that springs to mind).

I maintain a blog, but I doubt I have many readers (or any). I made a deliberate choice to not put any sort of analytics on the site so that I won’t be tempted to obsess about whether anyone actually visits. Some of the individual blogs that I know don’t get much readership that I read via RSS, I make a point of commenting on the rare posts to encourage the authors to write more. It doesn’t seem to make much difference although I’m sure they appreciate the positive feedback.

A lot of the delightful weirdness is gone. All the tilde sites with hand-made HTML and lots of flashing gifs and blink tags may have been tacky, but they were fun. I don’t get the kind of pleasure from most websites that I did back in the days of worst of the net which often surfaced delightful strange things that were completely unfiltered.
