Instead of #tweets or #toots, I’m calling this a #rumble. Because well, I imagine that’s the sound a mastodon would make. Trumpet is another (like an elephant), but you know who would want to take credit for that.

Also:
#bleat
#oink
#bellow
#yap

I’m also a big fan of bodily noises.
#fart
“Wait a minute, I have to post this fart on mastodon”.
I know, we’re very serious here.

@Ellinorianne #rumble is interesting. For now, I am going with the boring term "post". What I like about Mastodon is that we have a bit more flexibility than the little bird place. But I like your thinking process!
