There are different sections of the QB. As Candace mentioned, if you post something in the thread you will always be able to find it in the "Quick Links" area in the header of the Home Page, or by clicking on your profile to see your own posts.
Each section of the QB has a description of what it is for. I can usually figure out which section a thread has been moved to. For example, if there is a personal quality to the original post (such as questions about my experience with arthritis, or announcing arrival of a grandchild) it will be moved to the "Personal Diaries and Announcements" section.
I typically check my "Quick Links" first, then go to the bottom of the page to access the "Archives" and check out new posts in "Main", "General Chit Chat", and "Personal Diaries". Most of the other sections of the QB are of only occasional interest to me, but many people regularly check other sections.
