If we can find people to lead a sub community, and their is sufficient interest from that community, then I expect us to continue to expand the languages that we support. Our goal is making a platform upon which STEM communication can fluorish and this means allowing and facilitating content creation in which ever languages creators feel comfortable and audiences want to read.

I think that's a long winded answer to say yes we would love to support Mandarin or cantonese content. A STEM-cn sub community would be awesome to have IMO. Just need to find motivated individuals to spearhead that sort of effort.
