I don’t think social networking sites lend themselves to advertising.  The NYT has a story about a lackluster P&G/Facebook campaign.  I’ve covered this theme on this blog, but in essence, social networking is about communications, and every other communications form on the Web - be it email, message boards or chats - have not proven to be cash cows with regards to advertising.  Social networks will be no different.

2 - Monetizing video streams awfully reminiscent to monetizing search queries.

In 2000, I worked in the search engine space.  We all knew that a search query was a valuable action, but we didn’t know how valuable.  Google borrowed GoTo’s model and the rest is history.  While search conveys intent, video (and content in general) conveys interest.

I think video as a business model in 2009 will be awfully similar to 2001 when search as a business model took off.

It’s a matter of time.
