Google Fonts Redesign
It’s a big redesign of a site I’m sure all of use have visited many, many times. It even resides on a new subdomain: fonts.google.com.
Live typing samples in the search index for the win! There are also much nicer font specimen pages with clearer examples, cool/nerdy data visualizations, and pairing recommendations. Reminder that you may want to use a bit more sophisticated font loading than the snippets they provide, though.
