	Which requires that people type addresses in in the first
	place.  It's like these anti spam proceedures which require
	that you respond to a message that says you sent the email
	to let it through.  I doesn't work if everyone or even if
	most do it.

	No they make finding a unique id easy by leveraging a
	existing globally unique system.

	Which you have typed into the web browser in the first place.

	1 if you actually want people to get to you and not your

	There is a reason people put phone numbers in advertisments

	There is a difference between looking for a service and looking

	People may not know what a domain name is but they will use
	them all the time even if they are not aware of it.  Google
	Twitter, Facebook etc. all depend on a working DNS whether
	they make it use visible to user or not.
