When I listed these arguments:
* It encourages hoarding instead of spending as a currency.  
* It causes inflation.  
* People have pointed us to coins like Tagcoin that used Proof of stake and became wrought with technical problems regarding high orphan rates to the point that merchants no longer wanted to accept them.

I meant this the above points are what has been said that has been pointed out to us.  I probably should have put them in quotes although I was not directly quoting but summarizing the points that have been brought up.

Let me make this 100% clear.  I, personally, am not for or against proof-of-stake because I am willing to admit that there are other people who have more experience with proof-of-stake than I do.  We are collecting feedback based on people's experiences along with continuing out current plans and still looking for more people to pitch in to make things happen faster.
