For example: "This is a pastebin like environment for learning Hyperfiddle. Please namespace :idents with your username Schema changes are allowed To make a fiddle interactive, change tank.hyperfiddle.net to demo.hyperfiddle.net"
My mom no grok: pastebin, :idents, namespace as a verb, schema, "change" without a where to change.
Granted, this is a conversation between to engineers, so there's lexicon, but even listening, I get the sense that words get used without definition, or at least without a definition that speaker and listener share.
