Add Mastodon or ActivityPub

I need Mastodon support because most of my followers and the iOS/macOS developer community have moved there since 2022. While some still use Twitter/X or Threads, engagement is much higher on Mastodon. Despite being a niche community, it’s growing and highly relevant for our target audience. Even basic support for ActivityPub (Mastodon’s protocol) would be a valuable addition, as it’s well-documented and developer-friendly. This would make Vista Social even better!
