Danny Sullivan operates a terrific blog about Search. I noticed that the other day he took to task erstwhile Net marketing guru Seth Godin for doubting that there is something called a "search industry."

More info for Seth Godin: check out the SES New York show taking place at the Hilton New York February 29-March 3. All exhibit space is sold and the show is significantly larger than the 2004 version. Over 89 companies are exhibiting (I think this might very well mean that there is a search industry?)!
