Seems 2007 is going to be the year of niched portals and vertical search.
Microsoft is buying Medstory, a health information search engine, and furthering their move into niched portals and vertical search. In China they have started development on a job search engine.
Yahoo seems to be using the portal, community model with search ads as part of the monetization. Though they are trying to develop a business search engine as their primary perspective for the Chinese market.
Yahoo has created entertainment community pages for the Oscars; car fan sites using the manufacturers as support and advertiser.
This seems to be a repeating theme in the two months so far of 2007. Let's see where this all ends up.
