If you don’t already read Plait’s Bad Astronomy blog on Slate, I highly recommend it. Fascinating and educational, it’s like brain floss except way more fun. And because he actually enjoys discussion and bringing people into the fold, you may be especially endeared by his Twitter exchange with Greta Van Susteren over her recent bone-headed tweet about NASA/New Horizons.

Phil, if we ever meet, I owe you a beer.
