For almost every "web professional", the things they do are not complex. It follows then that the likelihood of this question (to a reader that doesn't know you) being asked by someone who simply doesn't understand what it means to be simple. The casual observer is further lured down this path of reasoning because of your implications that a plain form is somehow worse than something mediated by megabytes of javascript. In almost every case you'll find online, this isn't true.
