Stop Googling
I'm sure I'll be in the minority here, but a huge benefit of using libraries is that I don't have to know how they work, or care.  The documentation says 'call foo() with this argument to do bar', and that's all I want to care about.
I have other things to worry about (like my own code), than to want to dig into the internals of somebody's else's library to figure out something which should be easily documented.
