Shipping so fast you end up delivering a bad user experience doesn't actually help the user.

I feel like this needs to be strongly emphasized for the agile crowd that knows what speed is but sometimes forgets what quality is.

no one said that speed is the end goal. I said if you don't need to collect feedback, there is no need to ship fast. Of course the outcome is that you have a product with ideas pulled out of your arse instead of responding to users' voices. Having said it could still be good
