I just finished reading an inspired blog post by Stowe Boyd about something he has named 'Blog Trees'.

Please take a look, as his idea continues on very nicely from my earlier post about social commenting in Switchboard, and gives me even more ideas of how we can commoditise comments on a blog and tie them neatly into some sort of threaded tree or list.

The real thought here is that a wiki-like expansion of structure would be supported in this "Blog Tree" model. Any one participating (presuming they were granted rights to do so) could create a new blog, in context, extending the topics explored within an existing blog post. We would not be limited to the blog post/comment/trackback model, now in use.

I really like the idea of comments becoming their own blog post and can really expand on that.
