With so much of an emphasis on front-end frameworks and JavaScript runtimes, it’s time to get back to basics—back to optimizing every little byte like your life depends on it and ensuring your site can work, no matter what.

I love this idea! As someone who just launched a site that prides itself on being smaller and more efficient than the competition, this makes me smile from ear to ear. I'm excited to see what amazing projects come out of this competition.
