Libraries? Blogs?

I have to wonder. How might blogs be used in a library environment?

Perhaps a blog done by a library head honcho, e.g. director, could be a good way to share news in a timely manner, and seek contributions from staff. Communication is always a problem in work settings as large as PBCLS. Would blogs for each branch be useful? Do branch managers really have time for yet another responsibility?

Staff members with a strong interest in a particular author or genre might create blogs to share ideas with like-minded patrons.

Should there be PBCLS blogs created by patrons for patrons? I don't know. They might inspire so-called "adult" content that would offend other patrons. Maybe an old fashioned bulletin board (you know, Web 1.0 technology) would work better?
