I think it's D, through process of elimination, for these reasons:

1: It can't be [A] because Blurt is about as forkable as a truckstop hooker. (Be careful, trying to do so is dangerous and they will fork you back.)

2: I don't think it's [B] or [C] because I don't know what soft forks or lysdexia are.

3: This is Blatantly obvious. "Astonishing" in the same way as someone who tries to escape a bear by climbing up a tree. And it's not just marketing, it's whoever is making decisions about author rewards, ux/ui, and the vast network of complete clusterfuckery that is Blurtonomics. Do you think they are aware that their pyramid scheme is never going to work if they can't convince people to join it?

Sidenote: The image itself hurts my brain. Purely for less-brain-hurty reasons, I'd prefer if the vertical surfaces were shaded.

Thanks for coming to my Reddtalk!
