When I first discovered the draft post queue I used it pretty much as it was intended as a holding area for completed posts you don't want to post quite yet or posts that nearly done. I still use it in that way, but I tend to take to long to getting back to posts started back whenever. I am tired of seeing some of those posts that have been in the queue for a year or more. I need to stop procrastinating and finish the dang things. I am an unpaid professional first class procrastinator.
For older posts it often includes a major editing overhaul. Making sure that time references are updated, or sometimes eliminated completely.
For this blog there are a couple of book reviews. One I just need to find an appropriate quote and the other I need to scan the cover, and find a quote. I also have a DVD review from a movie viewing from a few years ago. If it wasn't a review I might consider it one of those long overdue expired reference things.
