Because the library, and variants, are pretty well debugged at this point. Most of the thread contributions here, including yourself, are actually asking about how to get your local configuration (hardware and/or software) correct rather than issues with the library proper. You're not actually asking questions about the library, but rather local issues using the library. That's why I made the distinction between "library proper" and your use.
Doing so makes it more easily search-able for others which suffer the same issue. It also makes it less intimidating for those coming after; such that they are not staring at a thread with a rather large page count.
Better questions. Why wouldn't you post your specific issue in its own thread? Do you have any information which indicates this is a library specific issue? Beyond all that, creating a new thread on forums, is general considered proper forum etiquette.
