The concept of bubbling up conversation to the top level of one's own published blog is fascinating. I didn't quite understand reblogging before reading your explanation, and I think that's the main downside to the scheme, but there is certainly value in making the act of commenting ALSO an act of publishing on one's own blog.
Yeah. It's tough to understand, and sometimes I feel that it detracts from the blog entirely (extended back-and-forth conversations start to look amateur), but it's a very neat system that gives you a lot of freedom in how you choose to handle interaction.
