I voted zetacoin two days ago and begin use it now.
No Premine
Based on latest Bitcoin 0.8.99 source
Block target: 30 seconds (20x Bitcoin)
Difficulty retargets every 4 blocks based on last 90 blocks (Quick difficulty readjustment)
Block reward: 1000 ZET, halving every 80640 blocks (about 1 month), not dropping below 1 ZET (inflationary)
Total coin supply: 160 million ZET + small yearly inflation
160 million coins will be mined in around first year
Thereafter around 1 million per year (inflationary). This small inflation is a better incentive to keep the network hashing than purely transaction fees.

Zetacoin is exellent, but the zetacoin website is not so friendly!
