I don't have much to hide and I browse my web safely, so I will not be using these tools. Anything I put on to the web I am OK with other people seeing. If you don't want the rest of the world to see something, don't put it on the web. And if it will damage your reputation or get you on someone's hit list, at least do it anonymously. AKA get a dedicated computer that is cut off from any information of you. Another issue with things such as TOR, is browsing security. You have full responsiblity on determining what is safe and what is not. Unless more security measures are put in, I would not randomly browse using different protocols.
