> This raises an interesting question: should email addresses be private? Addresses of buildings aren't private, and they're somewhat analogous as with many computing concepts.
There are several ways to look at that.
The organization that I work for considers anything that ties two pieces of information about a person together as private information. That is to say that a person's name is not private and a phone number is not private, but connecting a phone number to a name is private. In one form or another, an email is frequently tied to a name (e.g. the email address is based on their name, or an account record includes both a name and an email address).
Another way is to consider how accessible the information is. There was a lot of information that was not considered as private prior to the widespread adoption of the internet. One issue that I remember popping up in the early 1990's involved property (i.e. land) records. Historically, people had to go to a government office to access them but they were publicly available. Since they were publicly available, some governments made them available online. Once they were available online, the barriers to access were removed (e.g. having to physically visit an office) and the ability to abuse that information was vastly increased. All of a sudden, people started considering something that used to be considered as public information as private information.
