A link with quotations
Rather than always requiring your readers to hop over to another site to get linked information, you might consider quoting parts of a story or blog entry.
This is accomplished with a combination of <blockquote> and </blockquote> tags, which will set the quoted material apart from your own comments.
For example, Volokh offers this reason for the growth of bloggers’ audience:
Thorough coverage of a particular issue: A blogger who’s interested in an issue may cover it in more detail than a typical newspaper would.
You might then follow that with your response to the idea.
