Many times it happens that I post a question and then visit the newest questions screen on the site and realize that my question doesn't appear on that screen for as long as a couple of minutes on the screen. But the same is not the case with Stack Exchange.com. Is this status-by-design or a bug?
This has to do with the aggressive caching mechanisms that the site uses. Some of the earlier podcasts discuss details of the system.
Since there are so many more visitors to stackoverflow than chess.stackexchange the cache is rebuilt more quickly there.
