Like most human actions, blogging is morally neutral. A blog can be a source of great good or evil, depending on how it is used.
At its best, blogging is a wonderful vehicle for the sharing of information and a useful forum for debate. At its worst, blogging becomes a forum for the equivalent of intellectual masturbation – the deliberate misuse of the intellect to spew ill-considered opinions for no fruitful purpose. Far too often, blogging is the latter.
Snide commentary, ad hominem attacks, and pointless rambling are antithetical to the purpose of blogging. Good blogging demands a willingness to seek and explain the truth, and exhibits fairness and respect for opposing points of view.
