Seems that Ben Hammersley is <a href="http://www.benhammersley.com/archives/004201.html#004201">writing another book for O'Reilly</a>:
"Weblog Hacks". He's soliciting submissions of any cool weblog hacks anyone might have written.
(Thanks to Erik for <a href="http://nslog.com/archives/2003/03/01/why_buy_weblog_hacks.php">pointing this out</a>.)
Can you think of anyone who's whipped up cool blog hacks recently? That's what I'd like to know. ;)
