If he reads every comment in this thread, which I hope he doesn't since it is more productive for him to be working on getting things working, the people that continuously try to make things a personal attack are only going to make it more difficult for him to stay motivated to get the Mixing feature completed.
With the 1.5 patch Artos has shown that he can look at a problem, come up with a solution, and implement it. He could have left things at where they were in 1.3 and Stablecoin would have been on par with all of the other coins out there. He chose to try to implement a fix with 1.4, and while it didn't work entirely as planned, he was able to correct for it, and there is now a difficulty adjusting system that allows for fast and stable block times which means transactions are now fast and stable, even if a Mining Pool jumps on and then leaves. How many other coins can say that?
Artos will post when he has something to say. If there isn't any new news to post, there is no need for him to.
