Why does lecturing sometimes work?

Lectures can be very effective...so what do you think about that. At least some can...well at least one or two a year under the right circumstances, or maybe everyday if given by the right person and during the right time and...well...I know that some of my best classes, most memorable classes and teachers, most life changing classes have been lectures. So you can't tell me that lectures don't work. Some do. Why? This podcast was inspired by Ginger Lewen's podcast http://gingerl.podomatic.com/ It has been on my mind for a couple of decades and just when I thought I ended the rambling podcasts, here comes another! Peace everyone! Music by Runaway Hudson...check em' out!
