This document contains a Twitter thread from Patrick Stox discussing concerns and considerations around implementing AMP (Accelerated Mobile Pages) for large enterprises. Some key points discussed include: - AMP adds complexity for enterprises that have to maintain multiple systems and meet various legal/technical requirements - It may not be possible for some enterprises to implement AMP if they have content/functionality that does not validate - Adopting AMP requires buy-in and resources from many different teams within an organization - There are open questions around legal issues, impact on brands, and what would happen if Google discontinued support for AMP in the future.
