I think a fair number of us non-cs-ers end up in web development primarily because html/css is more accessible. I, myself, was more interested in design than coding, and I only learned the basics as a means to creating the designs I wanted. From there you might start learning some JavaScript, you might start learning some frameworks (like Backbone, or ember), and you might get fairly proficient with them... but I don't think the web attracts non cs people because it's "cool" or "hip".
