If someone would write a script that would work with… well, let’s say, just hypothetically, a software package like ExpressionEngine, that would allow an author to take full advantage of post-dated entries by storing a request for, and then sending, appropriate pings (to blo.gs, or blogrolling.com, or whathaveyou) at the moment that the post-dated entry is actually published.
That would really be cool.
Elouise Oyzon at Weezblog periodically preloads entries. And some of those preloaded entries attract prepublication (prereading?) comments. Check out the time stamps on the entry and comments accessed using the following URL
