 ## History and Philosophy
 
-This library is a rewrite of the [Twitter Ruby library](https://github.com/sferik/twitter). Over 16 years of development, that library ballooned to over 3,000 lines of code (plus 7,500 lines of tests), not counting dependencies. This library is about 500 lines of code (plus 1000 test lines) and has no runtime dependencies. That doesn’t mean new features won’t be added over time, but the benefits of more code must be weighed against the benefits of less:

 ## Features
 
-If this entire library is implemented in just 500 lines of code, why should you use it at all vs. writing your own library that suits your needs? If you feel inspired to do that, don’t let me discourage you, but this library has some advanced features that may not be apparent without diving into the code:
