I think the reason we're still putting combo boxes and radio buttons on things we call "forms" is a chicken and egg problem. We have the form building tools, so we use the form building tools. Because we're using them, people make them. And the trend continues.

I have a project coming up at my university where I will be designing a simple online game creation utility. I've been thinking long and hard about what kinds of interfaces this would require. All I know so far is I will not make it 'wizard' or 'form' based.
