.tel is about using existing infrastructure (the DNS) to resolve contact information. Will it make phone numbers as inconsequential to the experience of communication as IP address are to browsing the web? Discuss.
No. Phone numbers are unique. Names are decidedly not unique. Every look in a phone book for John Smith?<p>A .tel domain may be great for the first person to get a popular .tel name, but it sucks for everyone else. And for that reason alone, it has no chance of replacing a telephone book.<p>Also, it is an expensive, proprietary, unscalable solution to a problem that doesn't exist.
