I do know what you mean, but.. I also remember the heyday of developer blogging around 2004-2008 and this eager style of approach was pretty common then! (Some might argue that Ruby's why the lucky stiff might make Julia's style look dry in comparison! :-))

I'm glad people like Julia are fostering this approach and hope the number of developers excitedly communicating about things they just discovered increases again. As an industry, I think we need more of this now, more than ever, from developers of all levels and disciplines.
