Websites are websites. Brochures are brochures. Never the twain shall meet.

Not never. At one time both were deemed to be the same thing. Designers designed websites like they did brochures. In some circles websites that resemble brochures are called brochureware¹.

Over time the twain have grown further and further apart. They will never meet again with a few exceptions. Some people, like attorneys in many cases, get along just fine with a site that resembles an online brochure. But the vast majority of us need a real website, not a brochure site.
