I knew someone or the other was going to do this – its too obvious an idea. “Lets try replacing all site navigation with a tag cloud!”. I just came across this on the FlockSucks website – its by a company called 83 degrees – you can tell from their name that they go in for all things hip and Web2.0.
I have my own opinion on the topic, but am going to wait till you express yours. What do you think? is this a good idea? Is this the future?
As a note, even del.icio.us and flickr have a basic website perma-navigation.
