There's nothing wrong with a long & detailed post & such a post isn't necessarily non-concise - what matters is the information contained therein, which you articulated well, IMO.

That said, I suspect that majority of folks present on forums such as this, only carry the expertise of their own personal experiences & come here seeking the experience (& camaraderie) of others who've been down similar paths. A detailed question will tend to reduce the proportion of readers who've shared the same experience & therefore feel that they have something to contribute. There's also the factor that readers are likely dealing with their own issues & may find themselves overwhelmed by questions that are complex. Doesn't make the question any less valid, but is likely to reduce the number of folks who feel that they can directly relate.& provide insight for it.
