This could be a great place for people with strong reputations in certain areas, to put up their content and do mini-tutorials and classes to help spread their knowledge. They will have to spend time figuring out who those content providers can be and how to incent them to produce valuable videos.

Conrad – Our mantra is to let the market decide. Just as you read the back cover to understand who wrote a book before you sell out $20, we try to enable the market to judge who is credible and what is quality content.

Now if they could keep me from locking my keys in my car, it would be perfect!

The good thing is it’s cheap, but people will inevitably ask why they have to pay at all. People try to get everything free online; ringtones, books, movies, music, and hell, even porn.

It’s going to be hard to convince people to pay for this video content when they’re already using a medium that allows them to find similar content for free elsewhere.

Yes, for users this creates a different experience – just as the difference between “learning” by flipping on your tv and catching whatever the Food Network or HGTV happens to be showing vs. spending your time and money to go take a class, search out an expert, or go buy a book at Barnes and Noble. (As a side note, we do actually offer some content for free, including a set of Mobile Picks specifically for iPhone surfers and a Free View of the Day.)

History has shown that publishing has always been a spectrum of models from ad-supported to pay per content and every mixture in between. Entertainment content tended to be more ad-supported — e.g. when you wanted to be entertained you flipped on the tv or radio, while instructional content tended to be pay for content — when you need to learn something you buy a book, take a class, or spend a lot of time figuring it out yourself.

Truth be told, as an platform, we do plan to allow authors to offer ad-supported content, as well as other marketing alternative in the coming months. We just chose to start with the thing which they simply couldn’t so anywhere else — Create something valuable and get compensated directly for doing it.

Thanks again for checking out our iPhone site. We’re pretty happy with how it turned out. For anyone thinking about building their first iPhone site, we’ll also be publishing a post later today with our Top 5 learning from the experience.
