As this question comes up a lot, and continues to come up, more than 7 years after I started the blog, I'm glad he took the time to record it in this video, less than ten minutes long. Fast summary: You shouldn't block off time in your day for social media. Like email or catching up on the news, social media happens "between" the rest of the bits in your life - be they meetings, work, or anything else.
Like many people, I consume content differently on a mobile device than I do on the desktop. I often watch television, but at the same time, have my Nexus 7 so I don't miss a thing - levering what I've long called continuous parallel attention. In the discussion, we talk about how Google+ Hangouts have broken down barriers in communicating with friends, family and colleagues, and how I leverage Twitter for real time content and sports. Of course, I work for Google, but these are my individual words, and the objective was to be as transparent and real as possible.
