Social Media Kills MSN & Yahoo by Chris Trayhorn, Publisher of mThink Blue Book, October 23, 2009 The Web 2.0 Summit is currently running just a couple of blocks from our office. Yesterday, Mary Meeker, one of Morgan Stanley’s leading analysts gave a magnificent presentation on the economy and mobile Internet. Her entire pack of presentation slides is available on Scribd.com, but we wanted to focus on one in particular that you can see here. What this shows us is the way that Facebook and YouTube are absolutely killing portals like Yahoo and MSN. For those people who still aren’t buying the whole social media thing, read and digest this slide. Believe, my friend. Believe!
