this is pretty cool, but I never understood the appeal of “hey guys im reading this book”
It's more like:
You: Hey guys im reading this book
Random Guy: Hey! I'm currently reading this book as well!
You: Cool! Let me check out what else you like!
And that's how you find your book people and with them a stack of unread but cool books you need to work through.
Dry beans, peas, etc are also cheaper than buying cans.
