One of the problems with allowing comments on your blog is that somebody might post a comment that will get you in trouble because it's defamatory or libelous.
The US Supreme Court has unanimously concluded that federal law insulates Internet providers and websites against lawsuits for the inflammatory statements of others.
It's worth pointing out, however, that the ruling does not protect the original authors of defamatory material. In other words, defamation is defamation, whether it's done online or offline, which is how it should be.
What this ruling does is protect websites from being held liable for something others post up on the comments section, which is also how it should be.
