Mastodon does not "feel like Twitter" in the way that Bluesky does.
Maybe it's the fact that it's so server-centric: I've never felt like I could just enter a handle in the search bar and be confident that if the search comes back empty, that person is not on Mastodon. The same is true for search by hashtag or topic.
There is an old adage about MBAs and CEOs - if we a pick a successful company in some period, can we really say that CEO helped it become successful? Or maybe he instead impeded its growth and company could have been x10 times more successful without him? Who knows, can't be tested repeatedly.
Same with Xitter clones. Maybe copying Xitter quirks is not the best way forward?
