what's worse is that the narration is incredibly tedious. He goes on for 2 minutes about the problem jQuery Mobile is attempting to solve. We're developers. We get it. Keep it moving.
Just now I have the section on jQuery 1.4.3. He goes on for a minute with what could just as easily have been said with "It will fix several bugs. Those bugs are..." but yet he goes on about how important these bug fixes are.
Basically, just like there is an art to being concise in writing, if anything that's even more important in video because it's much harder to "skim".
Basically this is a 28 minute video that could've covered its material in 5 minutes tops.
