Is there an existing way to make blogs for nodes (not users)? I want to be able to set up blogs (or blog-like things, anyway) on arbitrary nodes -- imagine that you have a content type representing an organization, and that organization's owner can create blog entries about the organzation, its activities, etc.  This would not be a lot of code to write, but I'd sure prefer to use an existing solution than hack a new one together.

Is there anything out there like that?  Any experiences to report about adapting/hijacking the existing blog module for this purpose?  Thanks!
It is a little bit of a learning curve at first but you could use OG Groups for something like this. Make your organization node be a group and add an audience field to blog content type.
