Accidental Blogger is pleased to welcome Norman Costa as its newest author. Readers may have noticed that our blogging rate has fallen quite precipitously in the last year. Sujatha recently alluded to it and the possible causes for the slow down. We hope that adding a new voice to the blog will liven things up. Norman joins us here after a two-year stint at the popular blog 3 Quarks Daily. I first became acquainted with Norm through his writings there. I look forward to hearing from him at our forum.
