I agree re the mindset of hackers: finding some neat new application and knowing exactly what you want to do with it, only to have its mechanics and implementation details utterly obfuscated so that you can only do what the designers intended is an incredibly frustrating experience.

The current industry-wide focus on simplified UI and managed UX that has the effect of constraining users into presumptive usage patterns is quite obnoxious to hackers and power-users who want to be in control of their own experience.
