If you're not a teacher of writing (and probably if you're not specifically a teacher of elementary or middle-school writing), then you might not know who he is, but trust me--to lots of teachers, he is a god.
Here's a bit of what Barry Lane is like...
Now, I should have learned from Cathy Hall. Whenever I go to any workshop or conference, I should take Sioux-on-a-Stick, because a person never knows when they're going to be reduced to a drooling groupie and they desperately want their picture with the god/goddess and they never have a good hair day but they have no choice... unless they have their alter ego on a stick.
Of course, Cathy-on-a-Stick looks lovely. Hair perfectly in place. A blazing-white smile. COAS is attractive, just like the real-life Cathy. And Sioux-on-a-Stick looks very much like the real life Sioux. Except not so lovely as the lovely COAS.
