Concentrated mining by people with more efficient miners is bad for the coin, especially early on. That's one reason why I slammed your use of an immature PoW instead of one that is already well optimized.
At the end of the day you are right, we probably should have went with an existing PoW algorithm instead of creating a new one, but at the time we had good reasons for doing it that way and it seemed like a good idea. But it was a sub-optimal design decision, and if I could turn back time the one thing I would change is the PoW algorithm. But it's done now and we can't change it, so I don't know why you have to rant about it for 50 pages. I think we have got the point by now, you don't like new PoW algorithms. It's not like it's the end of the world, the long mining period will do much to offset any big miners in these early stages, and the private GPU miners will be made publicly available soon enough. All new PoW algorithms take time to be optimized, and complaining about it isn't going to get it done.
I beg to differ on this. Having a new POW algo is not the problem. In fact, it is an innovative move and it is a plus. Forget about scrypt and scrypt-n, they are becoming boring. Many of these coins are dying. Forget about X11,13,14,15..whatever. People would call you a clone. You have done well with a new algo. Fresh from oven. Smelling good! Give yourself a pat.
When you have a few miners having their own power private mining software, the coin ends up centralised within a few hands. This is bad. People do not have confidence when a coin is being controlled by a few people. You need mass adoption. The way to go is to level the playing field as much as possible. And this is what Catia has done. You may have set a bounty for a gpu miner earlier on and you would have ended up with fewer unhappy faces. Nevertheless, it is not too late. In fact, we are still at the early birth of the coin. You have proved to have good listening ears and you have attended to the users'/miners' needs. As more miners become comfortable and confidence of XCN, they would become holders of the coin. Investors would join in. This is when the value of XCN would grow steadily. We would be seeing a bright future in XCN.
