I really like the idea, but the two examples you shared are underwhelming. They just show up as two embedded PDFs in a plain page. I expected to see a wall of media and text, not a single document that could have been shared on any platform.

I tried it, and it feels clunky, to be honest. There's a good idea at the core, but it's a bit buggy and cumbersome for me to use. Sorry to be so negative, but hopefully the honesty is helpful. I do think it's admirable that you launched and that you've submitted it here. I've never made it that far. :)

What have you done in the way of user testing?
