NYMag.com put together a special Twitter Approval Matrix to show where famous oversharers fall on the Insightful, News-Sharing, Insipid, and Navel-Gazing Grid. Many of those the Frisky follows (for research purposes, of course) were included, and, for the most part, we agreed with their assessments. Julia Allison and Spencer Pratt are insipidly navel-gazing? We totes co-sign that tweet! Rachel Maddow is news-sharing and insightful? That’s no surprise. But poor Megan McCain — she’s news-sharing, but despite her best efforts, she’s also insipid. Keep clicking for sample tweets.
