Over the years I have received many requests for 'paid blog posts' asking me to promote this product or that particular program. I can honestly say I have always turned them down. While I could make money by doing so, I've always posted about those products I have personally used, and about those issues that personally care about.
While I don't post as often as I once did, what has happened is simple: Life! I have finished my doctorate, and I spend more time reading and exploring into areas beyond my own limits. I still do not allow guest posts, and I certainly do not post about products in order to promote them. There is simply not enough independence of mind among educators today. They follow any Pied Piper who comes along promising some new neat idea or product. I refuse. There's too much conformity among educators. Innovation doesn't happen through conformity; it happens when educators test the limits of what currently exists.
