Very timely post, Jeff. I appreciate the advice. I've been scouring the net for resources that make it easy to use WordPress as a platform for developing web and SaaS apps, a topic you guys have covered in the past, and was surprised that there really wasn't one site covering this niche. So, for my personal benefit, I've started cataloging what I've found on http://wpappworld.com.

I think it's interesting that this topic has gotten time on Matt Mullenweg's State of the Word keynote for two years now and there are still some that have strong feelings against the idea. I'm writing about what I find for purely selfish reasons and I wouldn't mind seeing more coverage of this discussion throughout the web.

Thanks for your great coverage of the WordPress ecosystem.
