I definitely am. If people are interested in this, I would like to make this more of a community project where everyone could voice their suggestions or even actual code / implementation / web pages / foundations, than just me arguing against the rest of the bitcoin community

Your idea about the fixed inflation rate sounds very interesting. In that case, the block reward will become bigger instead of being fixed. Although, the value of the block reward will stay fixed, so that probably would really be a better idea. Would eliminate the need for transaction fees.

Something that needs polishing is how the coins are put into circulation though. I'm not exactly fond of the idea of a Altcoin foundation, because I want the launch of this blockchain to be as transparent as possible. Even more transparent than Bitcoin's was. And compared to Bitcoin's, the coins would be more even spread. I'm not saying that the early adopters don't deserve those benefits they got with Bitcoin, but more even coin spread would make the currency more stable (at the beginning). Also, the project founder's should not mint any coins themselves before the launch of the project (IXCoin being the worst example).

Faster maturity (until the fixed inflation% phase) would be generally better, but also has it's cons.
