Should every library be actively maintained in some way, ad infinitum, even when best practices shift to anti-patterns? What is our obligation, as developers, for sites we know have been abandoned? And, most importantly, how can we best serve the many different users of the web while still giving developers new programmatic tools? These are the same questions that we continue to return to, and they have been at the core of discussions like progressive enhancement, responsive design and accessibility.
This is an excellent post and history lesson, giving the background to Smooshgate.
