We don't care enough to want you to give us constructive feedback - stroke associations

The only one I have seen that seems to want feedback is the British Stroke Association.
Here at the Stroke Association we are looking for a representative sample of people affected by stroke to take part in a reader panel to provide feedback and advice on our written information publications and help us to be really sure that they are meeting the needs of stroke survivors and their carers.
Reader panel members will be sent a range of publications by post or email to read at regular intervals throughout the year and will be asked to provide a range of feedback, via a method appropriate to your needs.
Another failure in our stroke world. Someday our stroke leaders will realize they are failing survivors. Probably because the associations are for doctors and researchers, not survivors.

ASA - Nope

NSA - Nope

WSO - Nope

A great writeup from Seth Godin;
