Just want to say I think zetacoin has a cool name and logo, and more importantly, I think the small, constant minimum inflation is a great feature to have in case bitcoin goes too wildly deflationary. (Not saying it will, but no one really knows yet.) The rate is so small anyway that its effect is going to be 99.9% psychological, making holding to infinity not seem like such a great strategy. Not saying that bitcoin will fail, but it's good to have coins with slightly different economic models as backups.
Disclaimer: I have been holding a bag of zeta for a while now.
