* Google properly encrypts traffic to Gmail and Google Voice,
but they don't encrypt traffic to Google Calendar. An eavesdropper
can definitely see your calendar transactions and can likely
impersonate you to Google Calendar.

generally go out for all the world to see, so there isn't really a
privacy concern. Twitter uses OAuth signatures, which appear to
make it difficult for a third party to create forged tweets."
