Yes I opened my account on July 10th 2016 so I have pretty much witnessed everything that has taken place here. In my view trying to appeal to more short term "investors" is not the way to go. There is nothing wrong with speculating but the main issue that we need to address is getting adoption of the steem blockchain. If we had 10 million users each needing about 30 steem for RC no one would be complaining about the lockup period. That is what we need to aim for.
As I mentioned in the post having a lockup period is not a problem for investors in the "real" world. You can make the case for a shorter period (like in the proposal) but saying that it's daunting for investors and is one of the causes for the stagnation of the price is a distraction from the fundamental problem that we need to address.
If someone can show actual data that proves the premise then we should go ahead with the change. Maybe it's not a big deal in the end but the case made for the proposal is weak.
