Not that there isn't a lot of good, free resources out there. Apple's documentation being the most important and valuable example. But someone has to fill in the gaps, and I will happily argue that it can be worth quite a lot of time and money to learn something correctly rather than waste many hours due to bad advice. I haven't looked through these in particular, but yes, people pay for things like this, and they can definitely be worth it.
Can you provide some examples of this?
Which is a highly successful screencast site.
For $9/ month you get vetted solutions to real world problems found in the Ruby and Rails domains. I see a similar offering in iOS land to be a win.
It's not that I couldn't google for the answers when I meet with a specific problem. Often I'm not aware that there is a problem because my software works but I'm missing out on a really awesome design pattern that I don't know about.
These productions help serendipitously introduce me to new knowledge.
- explains the problem, give you the solutions out there, then shows how to implement the solution he likes, also overviews and gotchas
- sometimes a topic is totally new but you might find it useful later! This is what I actually find most useful, since it puts new ideas on your radar that are in your domain.
- if i want to implement a new feature, I'll often check railscasts. Watch the episode while programming, it is like having someone walk you through the process before you do it yourself.
Screencasts are also my preferred way of learning something. If the instructor is a good programmer you always learn things much beyond the code itself.
