Well, if someone already knows everything which is in the issue, no - there's not a lot of value they can gain. However, they could share that knowledge by contributing the links to the information as they find them!

Similarly, if things are being missed and too much is focused on development issues, or community issues, contribute the links to the application stuff that you think is missing! Or we can introduce a new section (I always fancied "troll of the week" ;-p) for content if it doesn't fit in one of the existing sections.
