Snarky is the default setting in the blogosphere.

Defined in the Merriam-Webster Dictionary as "sarcastic, impertinent, or irreverent in tone or manner," snarky is the preferred attitude for commentary on anything and everything.

But what happens if snarky takes a week off?

It's happening this week, through a harmonic convergence of summer vacations: Keith Olbermann is off this week from MSNBC's "Countdown" (though Air America's Rachel Maddow makes a good substitute), Jon Stewart's "The Daily Show" and Stephen Colbert's "The Colbert Report" are in reruns, and, locally, X96's "Radio From Hell" is playing "best of" snippets.

What's a snark-seeking blogger to do?

Should I redouble my efforts at being sarcastic? Find unflattering pictures of celebrities and write obnoxious captions about them? Pick on local newscasters for their shallow readings of important news stories?

Or maybe there's another way. Maybe I can write a blog that's positive. A blog that celebrates the good things in this world. A blog that sees an old lady in the crosswalk and tries to help her across, rather than kicking her in the shins. A blog that runs on hope, not snarkiness.

Nah.
