Bill Burnham writes about Google Base:
Google is clearly putting into place the major pieces required to support its vertical search platform. Broadly speaking, such a platform requires 4 major pieces:
1. A big, highly scalable database that can handle lots of queries. This, of course, is what Google Base was all about.
2. Consumer friendly front ends to access these databases. The auto and real estate front ends are obviously the first of such front ends.
3. A large, robust, crawling farm. This is obviously Googles crown jewel.
4. A set of intelligent algorithms to find, classify, and flag listings. We have yet to see this from Google.
