The “complete” Web 2.0 directory is the self-proclaimed 'complete Web 2.0 directory' - who am I to argue otherwise. The only biggest gripe I have with this site is the fact that it fails to define Web 2.0 - in other words, how does one know which websites qualify for inclusion? Regardless, this neat site combines Flash & AJAX to display its 'comprehensive' collection of Web 2.0 sites.
