Isn't this actually what we also do here on this forum, discussing our therapy experiences? And many people who post here find the information and discussions quite useful (myself included, especially when I was in the early phases of my therapy). For ourselves though, probably not for our therapists, especially if the T gets scrutinized or fired as a result of this client group discussions - so in a way it is often bad for them. I can see how some biased supervision or other peer T discussions can also be bad for the clients in a similar way... Can be kinda 'us against them'.
