Why out loud
You can spot an answer without being able to produce one.
Re-reading finds nothing wrong. The page supplies every step.
Points come from your file, not from a topic name.
The forces act on different objects, so they do not cancel.
Clear, specific, matched to your point.
Rehearsal, made visible
Checked off the moment your meaning lands.
Rehearse it, or learn it
Feynman’s method: explain it plainly out loud, and watch for the place you get stuck.
Slides, notes, a chapter. We pull out the points you need to hit.
Three minutes, nothing to read off. Checked claim by claim as you speak.
What landed, what was too thin, what you never reached. Then run it again.
Grounded in your material
Every claim stays tied to a quote from your own file.
Correct, vague or incomplete in real time.
Thinking pauses come out of the count.
Keep at it
Every day you explain something out loud adds one to your streak, counted where you actually are rather than where the server is. Add a friend by their username and you each see two things about the other: how many topics they have built, and how long their run is. Nothing else, and nothing you have said.
