When it works for people they usually don't have questions about it. While they may be reading the post they don't necessarily sign up to boast about successes. People are fairly modest but like to offer the benefit of their experience but it's hard to offer the benefit of ones experience if we don't know others are looking for it. So it's much easier to mention successes when someone needs help and encouragement.
So most post will start with a question for clarification or help in understanding something. When there is enough of a similar topic then you'll find someone will start a thread with their experience. There are many gems that come out when someone asks for help.
