Totally agree with you about NP being very determined, however I am pretty sure that Edison didn't have shareholders that he was over-promising and under-delivering to as often as NP has. And while Edison may have failed with the lightbulb 1000 times before succeeding, he DID have a myriad of other inventions that WERE successful prior to the lightbulb.

Again, not down on NP no matter how it seems, just calling it like it is. We will choose to put our faith in his confidence, because honestly, aside from getting too frustrated and cutting off our noses to spite our face by selling our shares, we hang on to whatever glimmer of hope there is, knowing that the science is solid, and one day, either by finally doing a trial correctly or by dumb luck, our patience will pay off handsomely for those who suffer medically and for those who hold their shares during these frustrating times.
