Kathy Sierra, an author and blogger who I admire greatly, has been the target of some sick, harassing comments and blog posts. The blogosphere can be an engaging, fun and friendly place. I don’t understand the motivations of those who feel it necessary to use it to harass and intimidate others. Kathy is so freaked out, she’s considering ceasing her blogging. I hope she doesn’t. Those who use blogs to terrorize others should be subject to the same laws as those who use other means for such activities.
