SEO, Webdesign, e-commerce: you should do it all

Or none of it... The longer i work in this business, the more i feel you can either do it all, or do nothing at all, because you need to have a pretty good knowledge of say, webdesign, to do SEO, or of SEO to do e-commerce or... etc. etc .etc. Some companies do it all, and call it "innovative online marketing solutions", not completely right i think, but at least they're getting some of it :).
