From online chatter, it was rumored that Microsoft was going to shutter its 13-year-old Web forum site, MSN Groups. It's now confirmed: Microsoft is ditching MSN Groups because it's launching a new product, Windows Live Groups. But you can't upgrade. Rather, Microsoft wants you to "migrate" to Multiply, yet another social network based out in Florida, and sign up for Windows Live Groups too. Maybe they should have just pointed you to a better competitor. That seems easier. [Microsoft]
