Mike Cornett has a zinger of a new business pod/vidcast called What's the Big Idea? And guess what the first topic is? Presentation skillz! Ah, it makes the heart of a shameless self-promoter happy.
Personally, I could do without the music bed, but Gary Mull's tips are solid. Same advice I'd give, and condensed into five nice, easy tips in a free vidcast. Give it a listen, and let me know what you think. Did you learn something useful from this? Anything you'd add?
