Another consideration: it looks like those of us without fb accounts probably can't even look at lists or buy for friends / family. This is a bummer on a personal level, but also limits usefulness in cases where anyone who would see the list doesn't use fb or feel comfortable using it to log in. To the developer: please consider adding email-based login, or maybe just unique links sent by email for viewers without fb.
