using pieces that work well and that users enjoy doesn’t preclude you from also doing other things differently.

just because hacker news has usernames, comments, and voting, that doesn’t mean it’s “trying to be reddit”

there are countless little things one can change that make it an entirely different experience even if some features are similar.

just like hackernews to reddit, the experience i’ve had on mastodon has been a noticeable improvement over twitter. yes, there are comments and voting in hackernews, but the experience is noticeably different—and better—than reddit.

This isn't "shares some features", this is directly copies the look and functionality of Twitter. It may have some differences, but so much is the same you can't argue that isn't what they were going for.
