Comment or blog?

If you're reading someone's blog and you would like to comment on it, you have the choice to add a comment on it, or write a blog entry at your own blog with a reference (link) to the blog your are commenting.

I wonder which one is the best approach. If you comment to an existing blog, you probably lose track of all your own contributions leaving your own blog empty, or you have to repeat yourself in your own blog. If you comment in your own blog however, the comment is probably not read by the writer of the article.

So, I tend to have a slight preference to write your own blog entry and put a link to it in the comment of the other blog. It would even be nicer to have a "link" that works by value instead of by reference.
