People post for different reasons. Not all responses resonate with all posters. Not everyone is looking to have themselves spoken about in the third person or for advice from people who are critical. Some people are looking for advice, but not everyone. I do not look for advice, for example. I like to read about how others see themselves in therapy. I don't really care what others think about me in therapy.
Sometimes posting is done to help the poster work something out rather than for advice. I am not saying people should not post what they want, but I do think it is unrealistic to expect that just because one person finds one post useful, that everyone, or even the original poster will do so. Regardless of how much it resonates with some, it will not, and in my opinion, is not even probable for it to be expected to resonate or be useful for everyone.
