I used to think of blogging's reactive nature as a flaw in the medium. I've changed my mind, though. I've come to believe that being a literary parasite is no bad thing. I'd argue, in fact, that parasitism is blogging's most distinctive and probably its most valuable feature.
Bloggers blog for a host of reasons, but what sets blogging apart as a literary form is that it offers a writer an easy way to document his or her responses to their day-to-day reading.
