The nature of trends is to die out-especially on television. So last Earth Day, I was amazed to see Captain Planet, the star of the 1990s TV series "Captain Planet and the Planeteers," trending worldwide on Twitter. Don't get me wrong-I love Cap. He was one of my favorite "stars" to work with when I was vice president of PR at Turner Broadcasting. After all, he had great hair (how could you not love that green mullet?), a catchy theme song, and a message you could really get behind-and not just because it was my job.

Duran Duran's "Hungry Like the Wolf" seems like an appropriate song for this week and perhaps captures some of the sentiment I've been hearing in the Twitter-sphere, blogosphere and across the social web about Facebook's acquisition of Instagram. The cacophony ranges from backlash in the Instagram community about the app being gobbled up by the wolf [Facebook], Facebook overpaying for a company that has no revenue and another group wondering if Facebook is crazy ... like a fox.
