Given that Mastodon and Bluesky are becoming more accepted now, we've decided to just drop X entirely from the footer and link to the Mastodon and Bluesky pages for MetaBrainz instead:

https://mastodon.social/@metabrainz
https://bsky.app/profile/metabrainz.org

We could have two entries on the footer, or one entry that is "Mastodon/Bluesky" with the two links, I guess - maybe the second would make more clear that they are generally equivalent to each other?

— was:

"Change Twitter link to X on the MusicBrainz homepage footer"
Twitter is gone, it's now X.
