About What a difference a decade makes! As LinkedIn celebrates its 10-year anniversary, we're taking the chance to look back on the last 10 years -- and the next. What were you doing 10 years ago? How does that compare to where you are now? Where do you want to be in the next 10 years? Enter this month's upload contest and share presentations on what 10 years has meant to you. Be sure to tag them "in10years." The person who uploads the presentation which gets the most number of likes by the end of May 2013 will win a free SlideShare PRO account!
