From Jason Rosenhouse's excellent EvolutionBlog, O'Leary Proves that ID is Worthless to Scientists:
ID is a complete dead-end scientifically. It just sits there and does nothing. For scientists this an even greater defect than being wrong. An incorrect perspective might still lead you to something useful and interesting, even if just the discovery that our perspective needs to be changed. ID doesn't even do that.
That is the concluding paragraph, but the entire posting is interesting, so click on over if you are so inclined... and the comments over there are fun, too!
