If you're coming from Twitter, you might find crossposter[0] useful.
Shameless plug, I wrote a bit about my experience moving from Twitter to Mastodon[1]
I just signed up. I'll have to overcome a negative first impression caused by the label of the submit button - "TOOT!". Actually, the effect is even worse in French, which was my default: "POUET!", a choice with clearly grotesque undertones. Not a clever pick if the project aims to become mainstream. (But Mastodon is not an easy name either.)
