I have been trained by professionals in how to make good slides, so at least I know a good one if I see it. I have to admit that within the free software world that training is sourly missing. Too often slides are filled with text as if the presentation itself is supposed to be documentation, speaker notes are often not distributed at all. Probably this is partly due to trying to make the slides meaningful to people who did not attend the presentation. However, I have never had any trouble with LO in that respect. I would rather say to the contrary, all the bling in powerpoint tends to lead to horrible presentations. Moreover there are several slides in Michael's presentation that are prime examples of excellent slides (while others are horrible). Exactly what problem do you have making good presentations with Impress?
