One of the frustrating aspects of the #Fediverse remains the web-based cross-instance interaction. If I follow a link to a post anywhere on the Fediverse, and I want to interact with it in any way, the “flow” is still too cumbersome, especially when I want to interact with multiple different posts from the same instance.
The effort that has gone into #Mastodon to improve the UX from this side *has* improved the situation since 2022 (when I joined), but even on Mastodon it's still suboptimal.
