The Wall Street Journal underscores social commerce giant Groupon’s woes in a story that points out that Andreessen Horowitz thought the company’s IPO was premature, and has sold off its holdings. Fidelity might be starting to cash out, too. But Kleiner Perkins, Morgan Stanley and T. Rowe Price are still in or adding shares. Fortune takes the Journal to task for over-interpreting these “patterns,” or seeing them as a big negative on the whole sector. My own Weekly Update says Groupon’s headed for trouble if it thinks it can be an e-commerce technology supplier for local businesses. It would be better off selling them simpler marketing services.
