That is the question tackled by Bryan Chapell over on The Gospel Coalition. It’s quite a lengthy piece, but thought-provoking. I found the following particularly pertinent:
I recognize that the ethics of the internet favor the democratization and equalization of all commentary. A wiki-mindset assumes that the larger the universe of opinion, the greater the likelihood that truth will bubble up. But the Bible does not judge truth by consensus or establish morality by popularity.
A blogger may contend that he or she is not responsible for what others say in such open forums. But this defense can be compromised by the blogger’s self-interests. At sites known for their edginess, shutting down or refereeing incendiary comments may damage the popularity of the blog.
The “cock-fight fascination” that draws visitors to religious controversy creates ethical pressures for Christian bloggers who believe they best fulfill their mission by garnering more attention for their point of view. The Bible calls them to seek peace, but they have to multiply controversy (or allow commenters to do so) in order to keep their blog visitable and viable (Rom 12:18; Heb 12:14-15).
We will not have means to navigate these issues unless we again agree that the Bible applies in the blogosphere (Ps 24:1). With that agreement, we can examine biblical responsibilities that we personally assume when we post on the internet.
The biblical ethic that primarily should bind us is not maximizing pageviews but faithfulness. If faithfulness should require our failure to succeed in worldly terms, then loyalty to heaven’s priorities demands that we fail rather than disregard Scripture.
