Level 3: The application could ONLY exist on the net, and draws its essential power from the network and the connections it makes possible between people or applications. These are applications that harness network effects to get better the more people use them. EBay, craigslist, Wikipedia, del.icio.us, Skype, (and yes, Dodgeball) meet this test.

Level 2: The application could exist offline, but it is uniquely advantaged by being online. Flickr is a great example.

Level 1: The application can and does exist successfully offline, but it gains additional features by being online. Writely is a great example.

Level 0: The application has primarily taken hold online, but it would work just as well offline if you had all the data in a local cache. MapQuest, Yahoo! Local, and Google Maps are all in this category.
