Martin Varsavsky's blog post on time management is overall quite an excellent read even for those who don't have a private jet. But in particular, the way he uses social media is quite interesting to see: "I use social media to take notes, like I have an idea for a business and I blog it, I share it, I work collectively with people, social media looks like a waste of time for others but it saves me time, I recruit on twitter, I brainstorm on Google+ or my blog, I work inside social media, get ideas, its a sanity check many times, crowdsourcing saves me time."
