There is an easy solution . . . whenever offering video training, just make a PDF available of the content (as well as the videos). It's not hard to do.
Sure there are plenty of newbies who are just starting and who will learn something from every second of every video, but there must also be a large number of people like myself, who have been doing IM for a while, and are familiar with all the basics, but always looking to learn more. If I can skim through a PDF, skip past all the stuff I already know, and learn a few new things, then I'll do so, but watching hours and videos most of which are about things I know already, I will just say "no" to begin with.
