Hi if you're new to mastodon, and don't want to let go of twitter yet (believe me I understand) you can cross-post in both directions in a most-pleasant way using https://moa.party/.
If you do this, strongly consider turning on "Conditional Posting" and 'Post tweets behind a content warning'
This is the best cross-poster, in my opinion, and it's made by @foozmeat
@phildini alternatively, i can vouch for keeping the twitter acount, but write tweets for twitter, toots for mastodon.
that way, i open myself to seeing how the tone and feel on each network influences how i write the same thing. or, eventually, which things not to bother sharing on twitter anymore.
