Long Zheng, cool dude from Australia, put this table up on his (more famous and better written Blog). So i've decided to make a Kill List, what should Microsoft retain and what should they kill! And by kill, i mean the brand and service; by transferring current user accounts to the equivalent service (and add some <good>features to them).
So here is the Kill List
Some of services are hard to compare and in general need to be gracefully merged. Branding is something of a prick, but i'm sure Microsoft will figure out something long and confusing, such as: Microsoft Live Search Marketing adCentre!
Edit: let's not kill Live Hotmail.(see comments)
Edit Again: Yahoo Music Unlimited subscription service shuttered. Transfer of service to Rhapsody.
