When a website is in development and forming community feedback is super important because it guides the community in the direction that the possible entire community would like to see it go. Without feedback the administrators and staff members will simply keep carrying on typically and may not provide changes regularly.
I think that's one of the great things about Admin Junkies - Cedric is very open to feedback and we discuss all feedback. We may not implement everything, any may not implement it the day of either, but we do discuss it. This feedback and discussion helps us know what everyone wants to see and would like or benefit from.
My other part I'd like to mention the biggest thing is constructive feedback. It's hard to make everyone happy, but it is especially difficult to make changes if all you say is "I hate this website"... well what about it specifically, and what would you have us do differently? Change is important, but sometimes opinions are needed in order to benefit a community as a whole.
