Personally, I don't like it! A plain old (real) name, url and email address would suit me fine!

Concepts like OpenID on the web are only going to get bigger and bigger. Shying away from something because it seems too difficult is the number one way to become outdated in the world and have users move onto something else. It seems difficult, because it is something different, but that doesn't mean that it should be abandoned. In a few years it's going to be common to hear, "Create a separate login for a web site? Why, was this site created in the early 2000?" The shift of the internet being a series of separate sites to a massively interconnected system is happening more and more every day. Pretty soon the sites which want to segregation themselves from everything are going to get pushed out of the way for something else.
