I am at the Search SIG down in Mountain View listening to the founders of some of the new vertical search engines including Healthline, Simply Hired, Trulia and Truveo. There were nearly 20% people in the room who were building search engines. When I asked these panelists whose search engines are basically are scraping other sites, cannibalizing the folks that provide the “content” for their sites, what was their exit strategy? Answer – dead silence. I was saying this earlier in the day, on this Web 2.0 highway, there are three exits: Microsoft, Yahoo and Google. And that simply sums up the single biggest problem with Web 2.0. Niall says Google mentioned every five minutes!
