Nirav Tolia Cofounder, Epinions

Nirav Tolia: I think the next big thing, from a market perspective, is consolidation. I think for a long time people have believed that there would be millions, and if not millions, thousands and hundreds of thousands of websites out there. I think that's going to be true, but in the business world, I truly believe that many rollouts are going to occur. So the Internet is a place where being No. 1 is way better than being No. 2. And if you're anything less than No. 2, you probably don't survive. So all of these different spaces, whether it's the portal or auction space, the online advice space with Epinions, all of these different spaces are not going to have multiple competitors. The companies that you hear about that survive, are going to actually own their markets. I think there are going to be very few sites out there that are capturing all the value. If you look at the top-rated sites on the Internet today, I think the top 20 sites capture 90 percent of the total traffic. I think next year you'll see those top 20 sites starting to capture 99 percent of all of the traffic. I think it's a natural thing that happens in most mediums.
