The Grave Dancer of Telecom: IDT has developed a reputation akin to Zell’s a decade earlier. They picked up my favorite telcom, WinStar Communications, not too long ago. Now, they’re going after WorldCom pieces. I don’t see the synergy between WinStar’s fixed wireless network and the residential customers they seek to acquire, but I figure it’s worth a few bucks to see where IDT goes. After all, the original Grave Dancer was doing pretty well before the Simon acquisition. Forbes profiled IDT pretty well a few months ago.
