I tend to think of this stickied thread as more of a discussion of Linux in general. But if someone does have a particular issue they wish to discuss, I don't see why it shouldn't have its own thread. In fact looking at the first page of C&IT, I see three Linux related threads, each one with it's own subject. Linus Torvalds should sue, Privacy and Ubuntu, and Ubuntu 13.10.
We don't have specific stickied threads for Apple or Microsoft. However there's F@H and Let's see your desktop, both stickied.
