I think that is a great idea as long as there are the people available to assistant within the channels. As far as adding the channels, it’s a definite yes and should make it easier for people to find others that speak the same language and get clarification on things. I may be wrong, but this may get more people involved in the DAO, that may currently stay away because of the language barrier.
I have the same concerns as Existential, but to reach a more global audience should be a goal we continuously strive for. Otherwise the language barrier will be a unintentional blocker for people participating in our DAO.
Completely in favor, all the proposals that have an impact on destroying barriers will be beneficial in the long term, I also share the comments of @Canessa and @Existential14.
