Just discovered this service to cross-post between Mastodon and Twitter: https://crossposter.masto.donte.com.br/ testing it out with this post (toot? tweet?). Anyways I'm @peter_hebert on twitter and firstname.lastname@example.org on Mastodon. Peace.
@peterhebert I'm seeing more folks using it, and it just appears lazy; at least RT's and the like are irrelevant to masto as links and user tags don't copy across. For actual posts where you can correct the links a bit it's better.
