I just thought about identity-management on the internet and build the following figure:

It shows your identity as a person (including realname etc.) and connects different partial-identities to it.
A partial-identity is a subset of your whole identity-information. You create such subsets with nearly every service you use on the internet.
For example by using a social bookmark service, your partial-identity is the information about your preferred bookmarks.
Such subsets of your identity are not very delicate if you can’t connect them to your whole identity. If you are able to connect them, the information from the partial-identity become authentic. And thats a problem for your privacy.
So the best way to protect your identity is to avoid information which can connect the subsets among each other. And also avoid information which can directly map a subset to your identity. You can use for example different email-addresses for each service.
