We manage all of this on github (https://github.com/Google/WebFundamentals) and love getting feedback on what we need to improve!
It's your site, but if I meant fundamentals, I would call it fundamentals and start with fundamentals: HTML and CSS. If I meant building on the fundamentals, I would write about the standard uses of JavaScript to bring HTML and CSS to life. If I meant "newest things", I would call it a blog and talk about the newest things: recently implemented and incompletely supported APIs, such as notifications. Some of the newest things are very interesting as what they are: new things.
Maybe I'm missing something, but I don't see any reason to label a site "web fundamentals" and lead with something that has never been fundamental to the Web unless the agenda of "web fundamentals" is something other than teaching web fundamentals.
The home page needs some work, clearly and we can sort that.
