New React Framework site we just put up. Feedback, please!!

I have a few nitpicky comments.

Is validation not done yet? I noticed I can put anything into the email address bar, without any errors.

I like the gradient. It's a nice touch. I immediately noticed the undraw graphics, it's pretty obvious. Maybe I've just seen too many sites with them, so they really pop out for me, in a not so great way. On the other hand, most people won't notice...

The page is a little funky on mobile. The 'Our Approach' text runs into the graphic on small screens. The podcast page is all messed up on mobile. Nothing is stacking correctly. The hamburger menu also seems to be broken.

There is a bunch of weird whitespace at the bottom of the FAQ page on desktop. It's weird, it only happens when I navigate to the page from another link.

Good start, just a few issues you need to work through.
