Death threats against prominent blogger Kathy Sierra have set off what looks to be an unprecedented Internet-wide protest against cyberbullying. It’s a horrible way to raise awareness, but awareness has long been needed. I unconsciously previewed the news when I wrote “Predators vs. cyberbullies: A reality check” a couple of weeks ago. More recently, “when computer programmer and author Kathy Sierra began blogging about technology, she fully expected to see comments critical of her ideas. What she didn’t anticipate were online posts advocating her murder or sexual assault against her,” Business Week reports. Hundreds of bloggers have blogged their protests, and tech-education blogger Andy Carvin has called for this Friday to be Stop Cyberbullying Day and created not a new blog but a new social-networking site to mark the day. My thanks to friend, blogger, and tech educator Anne Bubnic for her heads-up on this.
