Oh he has many brilliantly told historical stories and on top, still gets his hands dirty and recently did benchmark of compilers. One of the few channels upon YT I'd recommend a sub.
This seems like as good a place as any to bring this up, if only to see if I'm the only one.
I want to watch Dave Plummer's videos but there's something eerily wrong about the amount his lips move (very little) versus his diction (which is very good). It sets off some instinctual discomfort I can't put my finger on. It feels like some kind of ventriloquism act.
That said, I've enjoyed his videos. I just wish his mouth movements didn't make my brain feel all funny.
I do get a sorta de-sync with lips and words in many video's, but then the system I use to watch them is hitting the wall of its life (core2duo) and the autistic spectrum aspect and facial hair will also play into that. I know they do for me and if you think first hearing yourself back on a recording is odd sounding, wait until you see yourself speak on video. Some people are in their element, others, you will get that underlying sense of awkwardness. Which for some (like myself) will talk fast and any facial nuance will be an afterthought long past most attention spans as they race to keep up with the words being spoken.
