Tiny design feedback: Make the border of a quoted cast darker to better differentiate from the new cast's text. 

They sort of bleed into each other, which makes it feel like a lot of text overall (when the quoted cast is text heavy).

I think think this is only an issue on web, bc the cast background gets darker (from pure white) when hovered over (not a thing on mobile). For a web fix I would copy Twitter on the border weight and color, the curve of the corners, and the second layer of shading on the quoted tweet when hovered over. Video comp:

Yes. Twitter is a good comp (it's what I initially comped against when I first wondered why it felt off).
