I think there's confusion because my original post was in reply to a very specific question about OLED judder caused by sample-and-hold, compared to stutter, which was in this case an artefact of the TV randomly switching between two different pulldown methods.
I would classify both sample-and-hold motion and 3:2 pulldown motion as judder. It's a continuous and repetitive break in otherwise smooth motion.
Stutter is a non-continuous break in motion such as a repeated or skipped frame that occurs in non-repetitive way - ie a skipped frame that happens a couple of times during a scene.
That does appear to (mostly) agree with both the rtings and HDTVtest articles I linked to above. Rtings did use both judder and stutter when talking about the same thing, but mostly call it judder,
