Teaching Online?

Today's Wired Campus Blog from the Chronicle of Higher Ed provides a post by Andrea Foster on adjunct teaching online drawn from a recent book How to Teach Online (and Make $100,000 a year) by Becky Brown who claims to have done just this. Brown's website does not say which classes she is teaching online. I wonder if any of these are writing classes? Granted that our MA's are eager for teaching jobs and that many of our students find online courses more convenient, still I wonder if this is the panacea that Brown claims.
