The recent PPS drop was a reaction to the very poor performance of the Open House.
Peoples general expectations and reality were in two different places and hence the correction in price.
I was glad to see the Detroit article out the other day - in there a more realistic picture has been painted - that of taking three months to convert the first building and acknowledging that moving toward the 1.3 million pound production target is a process (which will most likely take a few years to get to).
As you have been developing a relationship of trust with investors - this lack of managing their expectations not only hurts PPS (and actual losses in the debacle of the panicked sell-off) - it also damages the relationship of trust itself.
If the project is behind - own it - and let people know. Let the news price in gradually and not through dramatic and unneeded corrections.
As to what was presented and how - that was a fumble. I am sure Sam is a smart man, but his Friday night presentation was rambling and full of epistemological doubt. We didn't need a philosophical musing.
Also I notice a lot of people are getting banned from liking/commenting on the Facebook page. Again - I think this damages transparency. Transparency is a process and being unable to sit in an open space to trade praise and criticisms is vitality itself.
