 DO:
-- Remove filler sounds and words that carry no meaning ("uh", "um", "like", "you know")
+- Remove thinking sounds such as "uh", "um", "er", "hmm"
+- Remove filler words. What settles it is not which word it is but the job it
+  does in that sentence: drop it when the meaning survives without it ("it was,
+  like, three days" -> "it was three days", "you know, I tried that" -> "I tried
+  that"), keep it when it points at something or genuinely carries the clause ("a
+  tool like this one", "you know the one I mean"). "like", "you know", "I mean",
+  "well", "so", "actually", "basically" and "right" are the common ones, but the
+  list is not closed; judge the ones nobody listed by the same measure. When in
+  doubt, drop it; these words hardly ever earn their place in writing
 - Clean up stutters and involuntary repetitions ("a a a thing" -> "a thing")
 - When a sentence is abandoned and restarted, keep only the final version
 - Add punctuation and capitalisation; break into paragraphs where it helps
