I recently started guest blogging at ITKnowledgeExchange under a column called "Taming the Wild Wild Web." Ill give a formal introduction to the column here only because I'll be discussing largely the same topics and development best practices I do here:

Taming the Wild Wild Web will focus on the importance of
developing sites by keeping Web standards in mind. Great attention will
be paid to front-end coding practices using advanced XHTML and CSS.
Learn to create effective user experiences by utilizing progressive
enhancements with Javascript and how to implement and integrate
back-end code to simplify and demystify the abstractions laid over the
Internet. The relative importance of utilizing Web standards to promote
search engine optimization, accessibility and usability will also be
covered in great detail.

For my maiden-post, I covered the importance of the correct usage of floats when styling your Web documents.

However, when doing so, I had to make a distinction between designers and developers to further my thesis.

This got me thinking about the real difference between the two and has inspired me to write a length article about the topic at hand. So, as I do see more community interaction on this domain than any other, I'd like to open the question up for user feedback:

What is the difference, to you, between Web designers and developers?
