Tor/Privoxy is a big success -- why didn't Mixmaster take off?

[kevdog]

I'm seeing a lot of people using tor/privoxy for anonymising their internet connection. I just wonder in the same vain why Mixmaster (a way to send anonymous email) never took off in the same fashion. I used to a client on Windows named quicksilver (http://quicksilver.skuz.net/) to provide a very easy interface to send mail via mixmaster, but have never found an equivalent with linux.

Just a random ponderance.
