Let me try to answer these:
Yes I am at the HQ.
As far as regional promos go, I think there is a distinct possibility for that, but it would need to be once we had multiple markets well built out with P5's. Funny note, actually grew up near St. Louis, very familiar with that style cheese.
I have thought for awhile that this generation had a "dumbed Down" palate, but I think it has actually fragmented into 2 groups. The people who grew up with Mcdonalds, KFC, and Pizza hut who continue to think that that is gourmet food, and the other segment that grew bored with the common chains and have gone exploring. I think of those as the group most label "foodies". We have found that our base user group for Pie 5 tends to fall into the "foodie" group. As for the others, I think once they taste the product and see how neat the process of building it exactly the way they want it and eating a pizza direct from the oven is, we win them over. Just need to get them in the door.
Charlie got a great offer to go work with a great group. I know it was a difficult decision for him, especially as P5 is still in its infancy and has a very bright future. I know he will continue to follow its progress closely.
The Thin crust is distintive, and I know of no products that duplicate it on the market. I have seen several recipes that come out similar though.
As to the recipes, I currently Create Pizza Inn/Pie 5 recipes. Many of the traditional items were here already and will continue to be here, such as the crust. I continue to work on variations of things for both concepts.
