I'm too "casual" to submit a relevant opinion, I just want to add a little "-" to the yglukhov enumeration : Insensitivity can scares newcomers. Most languages are fully sensitive and most people are used to include the style as a part of the identifier and to use the style to reduce the need to find names. I don't know if it's a good practise but it's like a little barrier for newcomers. You'll need to show them practical examples to give a proof of how the insensitivity is better.
