These presentations are mostly wasted time. Blah, blah, blah. Get to the goods, already!
So, skip to the second one ... where's the "How to..."? In section 3?
Video is usually a huge waste of time, period. The typical reader can take in information something like five times faster that a skilled speaker can talk.
I feel the same way about podcasts.
The good thing about podcasts is that they can still be consumed while your hands or eyes are busy, when reading wouldn't be an option.
I realize some folks are able to focus on work while listening to a podcast, but sadly I’m not one of them. Anything auditory which I need to actively listen to breaks my ability to work (conversely, an IM doesn’t do that, just someone talking). About the only time a podcast would work but reading wouldn’t is while driving, and thankfully I do that rarely.
