If your website isn't already mobile friendly, it should be. Google today released the Mobile Friendly Test API, a tool that lets developers automatically and quickly see if their webpages are mobile friendly. Think of it as a useful instrument for what should be a mandatory business practice.
Changes to an API Terms of Service (TOS) are an inevitable part of API operations, and as API owners work to evolve their APIs, changes can often be at odds with the community. As some API seem to struggle with the best way to update, Google's approach appears to be more balanced. Google just updated its TOS for Google Earth and its popular Google Maps API.
