I can't create an account because it uses Facebook, I'll wait for the next version.
Is Facebook uniquely untrustworthy in this category? Is there anything about Gyroscope that makes it uniquely trustworthy, if only they gathered your data directly?
I completely deleted my Facebook account a few weeks ago and quickly am realizing how far-reaching their monopoly already is.
This point alone - which doesn't even include the many, many privacy issues FB has - is enough for me to say I will not use a service that requires a FB login.
