Museums and the Blogoshpere (homework)

http://www.archimuse.com/mw2007/papers/gates/gates.html

I was initally drawn to this paper as it was about museums creating blogs and I just created a blog...so I felt a connection. Simple, but you've got to start somewhere.

It did get me to thinking about the role museums have in the blogosphere. It seems to me that their entry into the realm goes against the original mission of blogs - to enable a free stream of thought outside of corporate and media driven and controlled outlets. Do does a museum blog, which is a controlled entry that must pass through several layers of approvals and editing before being released, a true blog? It would seem to fly against the notion of spontaneous thought and reaction. If this is the case, where do museums fit into the blogosphere?
