>"author and Microsoft Researcher Danah Boyd [...] Imagine being a Comcast customer and being unable to email somebody using Time Warner, or a T-Mobile subscriber who can't call somebody who's on Verizon. Why do we allow this with our social networks?"
That's a good question, Ms. "Microsoft researcher". Perhaps you can imagine a world where people can exchange documents freely and accurately without proprietary software like MS-Word. Or a world where consumers can put any OS they want on any computer without MS working with vendors to try and block them at the BIOS level. Or imagine people sharing calendar events easily without using MS's Exchange/Outlook formats. MS tried to hijack the web with IE (and did so successfully for years), and lied about their competitors to prevent diversity, locked out vendors from including Linux or other FOSS on machines, corrupted exported filters to make sure files to/from competitors would be partially broken. And the list goes on and on. Microsoft has been responsible for more lock-in and anti-compatibility than any other tech company, so perhaps I find it ironic that someone from Microsoft would ask us to imagine any kind of world of incompatibility.
