Facebook will launch a new ad platform for websites and apps I guess. In your website and your app, Facebook knows who is using it(thanks to their Graph API and iOS SDK). That is a huge opportunity.
Yeah, I agree. I think a Facebook ad network is on the way.
A Facebook search engine would be cool, but I don't think it's coming any time soon. I heard someone suggest they could have 20% search engine market share overnight with their 1 billion + users. What do you guys think?
