It's my pet theory that the availability of the Twitter-to-Mastodon cross-poster has harmed Mastodon's adoption by giving people an easy way to change nothing about their social media habits, and pretend like they have checked out Mastodon without ever being here.
Every time I bring this up I get responses à la "not all cross-posters!" and well, if you don't think it's about you, don't make it about you
