He didn't say libs were well documented. He said ruby libraries usually have the same or similar structure/coding style.

The point is that it's oftentimes easier to grep the source for something than to track down said thing in google.

SPECIALLY because ruby libs tend to be horribly documented, but most times with simple-ish code to understand.

And, moreover, if you see a library that does too many weird things and you can't follow, it means that probably the code is shit and it's time to look for an alternative :)
