Because economic incentives will follow where people are and so if you try create something new it will slowly degrade over time. We’re seeing it happen again with the “fediverse” that is already starting to show signs of business people coming in with ideas for how to monetize it and it’s only a matter of time before it becomes a mess.

But at a smaller scale yes. Get yourself a personal site if you don’t already have one. Post content on your own domain. Make an effort to link to other personal sites. Create a blog roll. Join a forum since a few are still around. Or set up one if you want to create space for a new small community.
