This is a great idea. It's a product concept I explored with a Zack Shapiro a few years ago called whosignedup.com, and now it's great to see this live with a larger product behind the idea. Looking forward to seeing how this evolves.
@hnshah I remember @ZackShapiro telling me about Who Signed Up and was eager to give it a try. I'll check out Drift Daily, although side note: the name seems completely unrelated to me. Sounds like a racing game.
