If you don't, check out the story in today's Investor's Business Daily about what Google has done. The company has bought a ton of dark fiber, and it has bought stakes in companies that do broadband over power lines and Wi-Fi. I know eBay ( EBAY) bought Skype, where the sign-ups are hot and heavy. But the switching costs for this kind of stuff are going to be seamless. More important, you know Google wants to be an Internet Service Provider (ISP) -- it needs to do that just to grow, and I think that it is a natural to offer an all-in-one package. I think this initiative, stealth as it is, has hit eBay, along with a slowing in its core business (the company's not saying it is going into the ISP business). I also believe that Google has so much money, it simply isn't difficult to pull off, even as Yahoo! ( YHOO) declined to do it because of its partnership with AT&T ( T). But that partnership was made before it was obvious that phone calls were going to be free and you'd need to monetize it elsewhere. I don't see how eBay can monetize effectively.
