Crystal ball gazing is a dud bust - but given Yahoo's search sprint v Google is pretty much over there are probably just a few ways they can go to differentiate tomorrow. Portal media one stop shop, getting increasingly personal, social solutions or mobile Internet leader.
Should they der think out of the box they might even merge with a nex gen social network (how about Ning?) - surprise the market and add juice to an otherwise languid search (pun intended). If not they're gonna end up with another dud media dude or worse Arun Sarin, who did not a lot for Vodafone and clearly doesn't get the mobile Internet - just check Vodafone Live!
