But each to their own.
jam , you produce some great sites, but do not confuse pretty with effective.
BTW some of your example sites displayed on your home page, JAM, qualify as being a minisite.
Yes, I do many mini sites, but there is a difference between the mini sites I produce and the ones you produce.
I don't confuse pretty with effective, but when making something more visually appealing makes it more effective, I don't see why anyone wouldn't do it.
I know something good looking will always grab my attention, get me interested, and increase conversions more then something not as attractive.
