I've seen this kind of thin-skinned, childish behaviour far too many times in the past. One instances, from years ago, really stands out. A well-known language learning blogger posted a review of a learning site (created by another blogger, with whom he had several disagreements). The review was generally positive, but the other blogger took undue offense to some of the criticisms in the review (which were laid out politely and accurately). He not only posted a snarky "review" of blog from whence the review sprang but his followers jumped in, castigating the reviewer in various online forums. While I never expected corners of the internet to be a revival of Enlightenment-era salons, I'd hoped that they wouldn't be virtual pile ons. I'm naive ...
