paulI looked up what "progressive enhancement" means. I found two definitions with two very different biases. The more I read tech-related writing, the more sensitive I get to this stuff.
MDN [0] has a very elitist definition, suggesting only the "best possible experience" comes from "the most modern browsers":
> Progressive enhancement is a design philosophy that provides a baseline of essential content and functionality to as many users as possible, while delivering the best possible experience only to users of the most modern browsers that can run all the required code.
Wikipedia [1], on the other, has a much "mellow" definition. This one has more of a semantic web bias, generally putting emphasis "web content first", and simply referring to anything more than that as an "enhanced version":
> Progressive enhancement is a strategy in web design that puts emphasis on web content first, allowing everyone to access the basic content and functionality of a web page, whilst users with additional browser features or faster Internet access receive the enhanced version instead.
