After my last post about mobile site development, I found two other resources that I thought were good and expanded on my basic thoughts about designing a mobile site.

Mobile Web Developer's Guide which I found on Network Solutions' web site.

And Get your website ready for the Mobile Web in 10 steps which I found in a Google search.

What I find the most interesting about developing sites for mobile devices is that it takes me back to when I was learning web development in the late 90's when dial-up was the norm and broadband the exception.  But it also adds more form factor challenges because of the size of the devices.
