I think the title is a little misleading ... but I understand that "Should Younger Developers with a hot and in demand skillset be paid more" is too long and not as interesting.

That being said, I don't really understand what the dev was upset about ... Its just good ol' supply and demand.

Being skilled at new hot technology is always a good thing. In my short time as a dev, I've seen the crazy salaries for WPF (.NET), Rails, facebook (if that counts) and now iphone/android developers and I'm sure this won't be the last time either.

Want to make $200k+? Pick up the skills that are attracting that kind of coin. Simple.
