On WP 1.5 (I'm upgrading in a couple of days), it's possible to change the timestamp to some time in the future, hit Publish, and WP will schedule the posting, and it won't show up until the scheduled time. I've confirmed that I can do it. Now I'm trying to figure out if I should do it.
Are there any downsides (e.g., pings not being sent, articles not being available via the ping or RSS, etc.) to scheduling the publishing of an article this way?
