Please keep in mind that the tor documentation makes it clear that you need to use end-to-end encryption to protect your traffic from snooping by the exit nodes.

Regarding your comment "If you use a service offering anonymity the truth is you may have something worth hiding" I have to ask -- do you put your regular mail correspondence in an envelope, or do you use postcards for all your regular mail? If you don't use postcards, does it mean that you "have something worth hiding?" Privacy should be a basic assumption regardless of the content of your communication.

Finally, using tor does not mean that you are "shout[ing] that you have something to hide from the rooftops;" it just means that it is nobody else's business what you're doing on the web. With tor, only the entry node and exit node know the final destination and contents of your communication. If you run a tor client on your local machine, then only the exit node can really know what you're doing, and if you use end-to-end encryption the exit node will not be able to either the content of your communication or even where or who initiated it.

Moral of the story: read the manual and practice safe surfing.
