It's interesting that Zealandia is just now making news; I've known about it for years (#GeographyWhiz #ZealandiaHipster), but the issue now seems to be whether this mostly submerged continent (of which the main part that shows is the country of New Zealand) should officially be considered a continent. What say you?
Keep in mind that "continent" has various definitions, one of which is simply "large geographical region that may be defined by culture more than geography". Zealandia is made of continental crust, so just because most of it doesn't show doesn't mean it shouldn't be a continent (in my opinion).
