Again, the service isn't ready but at this point right now feedback is crucial as we near launch. We strive to be the definitive service in splitkey generation.
I had never heard of vanity addresses until WhyFhy introduced me to them. The process I went through to create the public/private key was a breeze thanks to his instructions. I have zero experience in coding and/or brute forcing, so this was a neat project to be a part of. At no point was I asked for the private key. In my experience, no compromise in security. Now i've got a Vanity Address to show off and share my experience.
