This is just too bizarre. Tim O'Reilly is either the father of the term "Web 2.0," or he gets credit or blame for popularizing the term. For better or worse, the phrase has caught on. IT@Cork in fact is holding a conference about it the week after next.
Now Tim O'Reilly's lawyers have claimed they have filed copyrights on the term and have sent a cease and desist letter to Tom Raftery whose producing and promoting the event. Perhaps this is Tim's surprise gift to Tom who should be celebrating today with his 72-hour-old baby.
This just has to be one of those bone-headed things lawyers do when no one is looking. If it isn't, than I would predict that O'Reilly has just put himself on the fast track to reputation implosion.
