@alexwild Because this site has basically no members from Mali, or Niger, or even Algeria or Tunisia; no content in Kabyle or Songhay or Fulfulde (I have to work hard to even find toots in Arabic); because it makes it unreasonably hard to find anyone; because posting a linguistics question here feels like shouting into the void, while posting one in Twitter reliably gets well-informed replies from a variety of perspectives... There's a lot more to social media than ownership and infrastructure.
