Self-host your fonts for better performance
I'm usually the first one to sneer in disbelief at super users who 'go nuclear' and disable the likes of javascript and images when browsing the web, but lately, I've been experimenting with having custom fonts disabled (that is, fonts I don't have locally), and it feels to me that page loads are much faster, and in some case more readable (pages feel 'cleaner'?).The only issues I've come across so far is when a site uses font symbols, but overall, I've been pleasantly surprised.
