It's odd how tied some folk are to slides even when it's a completely inappropriate tool for the situation at hand.
On the viewing side as as well as the presenter side.
I occasionally workshops on various things. Some (not all) of them don't have any slides.
None.
On the grounds that the point of the workshop, as far as I'm concerned, is to pay a lot of attention to what I'm telling you - and do the practical exercises. You learn by doing - not by reading. A slide deck just gets in the way of that. It's a barrier between me and the class.
Every time there's one or two people who really hate that and complain about the lack of the deck. Not the quality of the workshop - that they're fine with - but the fact they don't have a slide deck.
Occasionally it's because they want to take away the deck and run the workshop inside their own company for free (and hey - I don't mind about that. Honest. It actually helps sales ;-).
But more often folk seem to need "a thing" to take away and look at again. Not so much as a learning tool, but as token that they were there.
I'm seriously considering making some physical "things" for folk. Maybe postcards with the key learning points on and a reading list. Just to see if that'll help.
