@Gargron Actually, the plural of status can also be status (not that this is better, tho).
And yeah, I also think that renaming toots to posts is somewhat a pity. It adds inconsistency, gives mastodon a representation for ignoring its communities wishes, invalidates lots of pre-existing toots that somehow reference the word "toots" (in a way, it isn't backwards-compatible, so to say), and removes culture and character from mastodon like removing the cocktail decorations from a cocktail party would.
Also, didn't the original pull request talk about way more UI naming changes than just the "someone boosted your post" message?
