Well, first off Zend.com has a new case study this mroning all about WNDU.com, the Web site of the NBC-TV affiliate station in South Bend, Indiana They use PHP and all to make updates to their site and to keep the new there current. The world is learning!
And, at the time I'm writing this, PHPHead.com and PHPNewbie.net are having some troubles this morning, so please bear with them and they will be back soon for your enjoyment. Thanks.
Update: PHPHead.com is now back up. So is PHPNewbie.net. It appears that the RDF from PHPHead.com was what was slowing it down.
