I follow many websites with my feed reader, the web is still very active if you're willing to go out of your social media bubble.

People still publish on the web, the problem is that the noise is unbearable due to the SEO crap. I predict a return of curated website directories and of "blog rolls".

Google could start banning SEO spammers to drive the cost and the risk up. The fundamental problem of the web is that spam is cheap, and the other problem is that Google's incentives are more aligned with the SEO spammers than they are with users.
