As I posted in the other thread, I had a lot go wrong in my personal situation, so I've not been able to do jack. Just got caught up, and I'll be more active after the 30th when my internet gets hooked up. Right now I'm relying on McDonalds wifi
Anyway, on the idea of switching back to pure Proof of Work... Interesting, to say the least. If you do that, I would recommend using one of the newer algos, like X11 or something that has the potential to be CPU mined, so more people have a shot at it. I know it was originally SHA (I mined it from the launch) but if we want newer people, ASIC's are probably not the best answer at this time.
I actually favor hybrid PoW, PoS like TEK and HBN. Fairly low block reward and fairly high POS, it keeps the chain moving even when staking is low, and gets a wider base of interest.
Anyway, at the moment I have little time, but I will be again very active starting on or about september 30th. Glad to see it still happening.
