So, to recap, there probably won't be a polyglot.city co-op, and this instance probably won't become a thriving multilingual community, unless some unexpected happens. Also, my personal interests are now geared towards other things and I'm not able to be the active community developer that this kind of co-op project would require.
Polyglot City is the right instance for you, if you're interested in languages, language learning and translating, or if you are multilingual or polyglot. All languages are allowed to flourish on our timelines. Welcome!
