The Zend Developer Zone has announced today that Joel Spolsky (of Joel on Software) will be presenting the keynote at this year's Zend/PHP Conference & Expo:

I'm excited to announce that Joel Spolsky, author, CEO, and blogger extraordinaire has consented to be one of the keynote speakers at ZendCon '07. Joel is not a PHP developer but he knows a lot about hiring good developers and building good software. It's the latter of the two that he will be talking about at ZendCon.

You can check out more about Joel's talk on the ZDZ post and check out more about the conference on the official ZendCon 2007 page (including how to register).
