Buying Yahoo will be the worst mistake in the history of the Microsoft Corporation. The Ichan boot recently connected with the Yang backside clearing the way for the catastrophe. Microsoft is a big, slow moving, well organised company founded by a brilliant strategist. Yahoo is a big, slow moving, badly organised company founded by an terrible strategist.
Microsoft are behaving like a kid who has seen a new toy. They have a perfectly good business making operating systems and enterprise software. Instead of focusing on this area of expertise they are tossing out half baked rubbish like Sharepoint to chase after a company they will never be able to integrate and will end up selling for half of what they bought it for, if they are lucky. Yes there is a lot of money in online advertising, Google may eventually be given serious competition from somewhere but certainly not from Microhoo, if it ever happens.
Buying Yahoo is the obvious but wrong move. They should be picking up companies like PBwiki, Connectbeam and Trampoline Systems to build the next generation of enterprise apps which will ultimately replace Office. Instead they are going to blow their entire pile on Yahoo for the privilege of managing its decline more efficiently.
