Need any more convincing that you shouldn't run your presentations by simply regurgitating the badly-formatted content you threw up in awful colors on your PowerPoint slide? Check out Jason Olson's comments covering Tech Ed Day 1, VS Team Systems, Connected Systems, and Software Factories.
You may have great ideas, and you may be smarter than the average bear, but you ain't doin' nobody no favors if you can't get your message across to the audience. Do some research on presentations. Tom Peters' "Presentation Excellence" is a good start, or Drew Robbins' tips, or Hanselman's.
If you don't, you'd better hope you don't have folks like Olsen in your audience who will skewer you on your feedback form, or worse yet in a public arena like a blog.
