At this moment #Wikipedia supports many more languages than indigenoustweets.com. I can imagine that having tweets in our languages is something that is of interest to our language communities.
Kevin Scannell in this interview with Brian Lehrer is quite clear: he is interested in every small language. It might be an idea to link to Indigenoustweets on project like OmegaWiki and translatewiki.net where portals can be found for many languages.
