I assigned this issue to @fionataeyang . It's not urgent, but sometime in the future it would be nice to also take care of this.

Hey, Nina & Alex,
I don't understand about facebook card and twitter card. What is this using for? Do I need to design or just only write the content something about it? Like share card?

Oh I think I know what it is. Will research it later. :)
