Greeting from a wet and grey Ireland...

New to the community (couple of weeks) - about to set up my second MN. First one working like a charm thanks to Tao's guide.
Amazed by the effort both in terms of dev work and online presence (Tao/Tungfa etc). Equally impressed that any attempts by FUDsters just seems to galvanise the community even more.
Just a generic (probably stupid) Q. With the MN rewards scheme going higher % wise - at some, when difficulty increases, will it not detract miners from...well mining? Would it make sense that MN rewards decrease in future if it results in the overall health of DRK?
