Show HN: I made some free screencasts on iOS dev, should I make more?

My thoughts are that the Cocoaheads meetup i go to has all sorts of really interesting talks about advanced topics, but a lot of people who attend are just beginners, dipping their toes in iOS development, and it'd be helpful to show them the ropes outside of Cocoaheads (so the pros don't get bored!).

But rather than the typical beginner stuff you see on the internet which teach things that you wouldn't really use for advanced apps, these would teach good principles from day 1 - at least, that's my hope.

Anyway, i've made 2 screencasts, and i'm curious to see if there's any interest - if there is, i'll make more.

Cheers all :)
