Private Blogging

Is private blog a blog?
This is question has out there since blogs came about and still can elicit religious debates. Sometime back there was this debate between Jeff & Robert on whether private blogs are blogs? This discussion started the way in which MSN was counting blogs hosted with it.

Many popular blogs (including blogspot) have long provided the ability to keep blogs private or to a set group but they are not flexible enough to set the authorization at a granular level of an individual post. Now there is a new player called vox in the market who provides that. This may be the way to go as more and more people to take blogging but don't want everything open, but at the same time want to maintain a single blog.
