Thanks for this. Yes Twitter has blocked engagement with posts containing Substack links as of ~this morning

A few more Qs:

—What other user niches should I check out here? (i.e. what other communities have a notable presence?)

—Any further response to the Hindenburg report — or any development to know of since it dropped?

—Thoughts on Jason Lowery’s Softwar thesis?

—What have you read recently that’s shaped your thinking on the evolution of the internet?
