The way I see it, and I'm just one voice, folks running over to b-sky are doing so because they want "the party" to be in a single building with an announcer saying, "Here's so and so" or "Take a look at this person". Most (not all) bsky people are there because it's too difficult to get the likes and retweets for their level of desired popularity.

Masto users don't give a sh** about popularity, they care about substance: substance in the people and substance in the content. Likes, boosts, and re-toots don't mean anything. We're fine hunting for what and whom we want.
