⚡️48: Reconsider First Meaningful Paint, learn performance and more.

Calibre Performance Newsletter #### PerformanceNewsletter
#### Issue 48
#### Editor’s Note

Web performance is a specialised niche. Often, it’s challenging to convey what performance means to someone outside of our bubble.

Changing the way we name and define web performance *might* be useful in opening up meaningful conversations and popularising the importance of our work. 

As much as conveying ideas in an accessible language *is* essential,** the importance of web performance will not be popularised until it’s recognised as a prerequisite for equality on the web.**

Equal access is a human right and so are accessible and fast experiences.

#### article Is it time for a Web Performance rebrand? ## Think about rephrasing web performance [Simon Hearne](https://twitter.com/SimonHearne) ponders if web performance needs to be renamed to gain more traction outside of the people already deep within the field.
