We are all volunteers that put in hours of our time as a free service to you. If you don't like what we do, that's fine. But know that when you criticize our efforts it comes off as ungrateful. Which, at least for me, makes me want to donate less of my time to make you happy. This also applies when comparing our accomplishments to those of others. There will always be people who can do things better, there is no need to rub that in.
EDIT:
I wouldn't ban someone for sharing their opinion. I might get mad about it (as you've seen) but I wouldn't ban someone.
Not sure what there is to hide. As @Noob Saibot said, this event seemed rushed because a lot of it probably was. Ideas were still being discussed up to the last day before the event fired. I know that my major contribution to the event wasn't done on time, and now probably won't ever get done. I have been steadily losing the drive to work on pso, since it's often something that will just get torn apart by people who know nothing about what I'm doing or what it involves. It's hard to care about something when the people you're doing it for aren't happy with what you produce.
