Social Networks the new Search?

Now I’m not talking about Social Search but social networks.

The Cyworld’s, MySpace’s, and other hundreds of niche networks are turning into the “new search”.
“Ad Spending in Social Networks will reach $865 million in 2007.”

MySpace getting at least $525 million leaving the rest to the niche networks.

Will Social Networks be dominated by the big gorillas, or will smaller players have a stronger play?

What will happen in 2010 when Ad Spending in Social Networks reach $2.15 billion.
Internet consumers are embracing social networks the way the present and past consumers have embraced search.
