I like this service. I have been thinking about doing something similar myself. Though, I think it would have been better if it was marketed as a secure place to store private information.

Also, it would be great if this service had its code audited on frequent basis by a trusted 3rd party.

An iPhone app to synch my personal information locally would be awesome too. This way I could access my information even if I am not in front of a computer or don't have net access.
