The internet is really awesome, and blogging is also really awesome. There is just such an array of ideas and opinions the world over, depending on cultures and contexts and education and exposure and experience. Blogging emphasizes the right of everybody who has an internet connection to express their opinion and put it out there. Everyone has a right to allow comments and start a dialogue, even getting belligerent and offensive, everyone has a right to disallow comments and make their expression unilateral.

On the other hand it also promotes the right of anyone to prove they are dead wrong.
