So...one of my favorite websites (ever since I was in college) is www.despair.com. It is a site for your inner pessimist. They make "demotivators," which are basically posters (and t-shirts, etc.) that satirize "successories."
One of their latest demotivators...or, at least one I hadn't seen before (I haven't been on the site for a while)...is about blogging, in their typical barbed wit:
Isn't that the truth! ;)
