Text blocks are a new beta feature for Muse. Mark and Adam use the opportunity to discuss the origins and philosophy of text in computing, including text as a datum in environments like wikis, REPLs, and social media; the writing workflow of collapsing spatially-arranged ideas down to a linear text buffer; and company memo culture. And Mark shares his vision for how the Pencil could become the X-Acto knife for fast text editing on a tablet.
