Sorry to hear that Facebook Connect is a non-starter for you -- FWIW, we only use FB to to make adding friends easier; otherwise, people would have to manually enter email addresses, or select Twitter follows (which tends to be a less complete superset of one's real-world social graph). We never post to you or your friends' walls or anything annoying like that.
We're looking for ways to develop a solution that would both allow people to use it without a Facebook account but also seamlessly add friends, and trying to figure out if that's possible. Appreciate your feedback, and sorry that you weren't able to use the app.
