I set up a couple of channels, one for people I tend to interact with a lot, one for people I loosely follow. Both a combo of IndieWeb, Mastodon, Twitter and RSS feeds, mostly of actual real people. The other stuff I haven’t moved yet and is mostly institutional feeds.
When I get a social media urge, I’ll check the first two groups. If empty, I’ll maybe check the rest, or read an article, or just do something else.
The best part is avoiding anything that has an endless stream of fairly random (but tantalisingly, possibly interesting) stuff. As Ton points out, anything *really* worthwhile will invariably end up in a feed in one of the first two groups sooner or later. I’m feeling more intentional, less flighty of attention.
