What is needed imo is a bullet proof UI/UX design that makes it impossible to not understand what's going on or make anything that might interfere the initial anonymizing process. When that is done, PR machine can start recruiting new blood, not before.
Amen! I'm now anonymizing another 10k coins and I'm thrilled that the tech is working, even for large(ish) balances. That said, the UI isn't ready for prime time, and it really should be bulletproof before risk averse, normal users are invited to take it for a spin.
