Posts that have been highly anticipated or expected, or are at least obvious in retrospect, something that would result in a "why hasn't this been done yet?" reaction.
Contrast to pool #1823: Wow That Was Fast, when it happens much sooner than expected.
Within each post, a link and/or an explanation should be ideally provided so that the context can be understood if it isn't obvious from the post itself (image, commentary, tags, etc.).
