Gil brought my attention to a recent article by Zvi Frankel in the Jewish Observer warning about the dangers of blogs, and asked if I could make some comments (Zvi Frankel, "Blogs: Transgressing a Major Sin ‘In the Name of Heaven’: Possibly a Lack of Chinuch?" available online [with permission] here [PDF]). I think the author made a number of valid points, which I hope to use as a starting point for discussion of some of the unique dangers as well as benefits of blogging.
…While it is possible to spread a rumor secretly, it is impossible to denigrate someone on a blog secretly. Transparency and universal availability are the defining characteristics of blogs. Any responsible blog, like any medium of communication, must give a right of response to anyone whose reputation may be damaged by its content. But the truth is that due to the large number of blogs, even someone who is denied "equal time" on a blog which attacked him (or her) has ready access to equally public forums to present his/her side of the story.
So while blogs are an ideal medium to spread lashon hara, they are an even more ideal medium to refute lashon hara. When rumors are spread furtively they have tendency to be vague, rapidly exaggerated, difficult to track down and nearly impossible to refute. But when they can be precisely tracked down to a public blog post, there is a full opportunity to make a proper refutation.
I think that we can all think of instances where blogs, including Hirhuim, have been instrumental in publicizing pertinent and reliable information defending people against hurtful and unfounded accusations.
Another important point is that blogs are not only a vehicle for discussing people. They are at least important as a forum to discuss ideas.
I love this Jewish Observer piece. It calls on the Orthodox community to have a "zero tolerance" policy for blogs.
