#### Editor’s note
|
| |
|
I have been thinking a lot about how we talk about web performance, even starting with the term itself. What is web performance? Frankly, I always found it confusing—we can interpret it in so many ways.
|
| |
|
|
Following the curiosity to why we (the *#webperf* community) struggle to popularize speed outside of our own, often developer-centric circles, I found something curious. **People don’t search for „web performance”.**
|
| |
|
|
Language is powerful. The way we communicate and describe critical concepts behind speed will significantly affect whether others can understand and adopt them.
|
| |
|
|
If we use jargon and exclusively assume technical (expert) audience, we will never reach critical mass interest in speed. **Assume no knowledge, but expect curiosity.**
