> From what I can tell, there is literally nothing to show if you don't sign up. The site is entirely social. You have a feed and recommendations which are shared among friends. It's basically like saying there's zero chance you'll sign up for email if you can't see it beforehand.

If people weren't able to understand how email worked before signing up to it, you damn be sure that no one would sign up for it. But email is ubiquitous enough today that people don't need to understand how it works before signing up, because they likely already understand it.

But "social media for books" is different. Show me how the feed looks, show of it looks when people are using it. It's likely I either ignore it because I can't understand what it would give me without viewable screenshots about how it works before, or I sign up and land on an empty feed, getting discouraged from even using it because it's so empty when I first arrive.

Showing people how a product works before asking them to sign up is not a big ask, and something vital especially when trying to get people to sign up and commit to a new social network, when there are new ones created everyday.

People just want to see how stuff works before, and it'll take a couple of hours tops to add to the landing page.
