I have a suggestion for Bonfire:
Using boundaries for multi-language support? Posting memes in English, opinions in French, etc., so people get to choose which language(s) they prefer to read, instead of setting your language(s) in stone, i.e. in your profile.
You could totally use circles and boundaries to post things to a subset of your followers based on the languages they know, though I think it'll be worth adding a seperate feature to indicate the language of a post, and to be able to filter your own feed based on language(s).
This is a bonfire demo instance for testing purposes
