I'm a developer, but I also have a design background; I've been asked to take over site design on the e-commerce site I've been working on for a few years now. There's a lot I'd like to change, but, the fact is, I'm primarily a software developer now. I'm looking to get a refresher on good e-commerce site design, and I was wondering if anyone here, with a programming background like myself, knows of or uses any good resources for such a thing.
I realize that all answers I get here will be from a developer's perspective, so I'll be sure to check some business-oriented and design-oriented sites like stackoverflow to see what professionals in other areas might like to use as well.
