I read on Slashdot that CMP trademarked the term ‘Web 2.0’ and promptly started suing people who use the term in association with their conferences. CMP and O’Reilly started the Web 2.0 meme, I believe, with their conference of the same name. It’s become clear that the term in fact has zero meaning. It’s an interesting exercise to ask several people what they think it means. The best consensus you’ll find is it means “cool” or “modern”.
I was already tired of the term, and now I have a good reason to refuse to use it any more. I just removed all of the web2.0 del.icio.us tags I had and replaced them with tags I wouldn’t be embarrassed to see a couple years from now.
