We've rolled out a small but mighty features: you can now add rel='me'
links to your Buttondown profile, just by adding the URL to your "Your URLs" setting under Design settings.
This is a small but mighty feature that lets you assert your identity across the web, and it's a great way to signal to search engines that you're the same person behind your Buttondown account and your personal website.
Even more than that, it means if you add your Buttondown profile to platforms like Mastodon — and then add your Mastodon URL to Buttondown — both apps will add a cute little "verified" badge next to the link.
