I just posted a link to the statusboard on bluesky and noticed we are missing some nice meta tags to display links better for social. Before I forgot about it I wanted to open an issue.

Yep, it's something I've been thinking about adding to the statusboard, along with the possibility of adding a custom logo and other things.
