I gotta say, and I know you work with Matt Barton on this, one of the things that makes his videos near unwatchable is his plugs for the books *before* the videos talk about what they're supposed to.
Maybe this is a US/British thing but if the plugs came at the end, instead of before the meat of the video, they'd be easier to watch. I have yet to finish a Matt Chat video for this very reason.
My two cents.
