Public CDNs Are Useless and Dangerous
It always annoys me when a site hangs when it tries to load something from <i>fonts.googleapis.com</i>. Developers need to use a system font stack which loads fonts from the system itself instead of remote web fonts. On a fast connection you don’t notice it, but you will notice it on a slow connection, and the majority are on slow connections. Developers need to deliberately use slow connections and see just how responsive their site is. Don’t develop on a hyper fast connection because you assume the site loads super quick and overlook latency issues. I think you can emulate slow connections in browser devtools so there is that.
