I’ve been hoping for this! My favorite tech writer, @molly0xfff, just wrote a great intro to RSS: https://www.citationneeded.news/curate-with-rss/
@FontsInUse has long provided RSS feeds for many aspects of our site. Not just the Blog and Uses, but also any typeface, designer, foundry, or tag. It’s a great way to get notified on stuff you care about.
And of course, it’s not subject to the whims of corporate social media. This benefit of RSS was a big part of our recent announcement (https://fontsinuse.com/uses/63903/fonts-in-use-is-not-active-on-instagram).
