Information is so free that the noise to signal ratio is trash. It’s worth paying for a solid channel.
Somehow I feel a model marrying journalism and industry certification could work. Ie if you read and do some examples from every magazine then every 3 years you’re very likely to pass a certification test from the magazine.
Unfortunately, lots and lots of quality publications will continue to go out of business. When information becomes radically more free to distribute, the economics of publishing are upended.
