As a published mobile developer watching a huge daily churn rate on my free app's downloads, all I can say is I haven't been this excited to watch a video of a guy with a headset mic.. ever. So.. signed up and thanks in advance :)

.. edit: but you need to fix your audio. Your mic is using a noise gate to try to block background noise when you aren't speaking. The effect is like someone turning the mic on and off at the start and end of every word you speak. This makes it very hard to focus on your content. It would be easier to listen to you if:

- you had a single $20 dynamic mic a foot or two away from your mouth (or one of those $50 USB mics marketed for 'podcasting')

- speak louder (as if you were in a meeting)

- minimize background noise in the room.

If your floor is hardwood put a blanket down (or hanging behind the mic) to reduce reverberation and use audacity's parametric EQ to filter everything below 100hz and above ~30000hz (tune to taste).

As it is I got a few minutes in and decided to read the script instead (thanks for including it)
