This seems to be a sure-fire way to end up with slides that are far too wordy. When presenting from such slides the audience reads from the slide instead of paying attention to the presenter. It also facilitates using the slides as a crutch instead of preparing for the presentation. Inexperienced presenters often read straight from the slide instead of elaborating on what the slide offers. I prefer to keep the slides simple but prepare a detailed handout. One recent presentation that I delivered had only 8 slides but the attendees received a 34-page handout. I like for the attention to be on me when I present, not on overly wordy slides.
