Among a crowded field of Internet phone providers, Skype has turned heads with its unique blend of technology, grassroots marketing and rapid adoption. Sixty-five million people have downloaded the free software in the 18 months since Skype launched its product. In recent weeks, there’s been a spike in complaints about the company’s first commercial service–SkypeOut–that lets customers cheaply make calls off the Internet to ordinary phone lines. Aside from having to wait days for accounts to be credited–as dozens of customers have complained–many SkypeOut users say their conversations are disrupted by a two-second delay between someone speaking and being able to hear what was said.
