Between scarcity and abundance, there comes—you guessed it—a tipping point, and so who better to headline this year's "Scarcity and Abundance"-themed Pop!Tech conference than Malcolm Gladwell? The pop sociologist will be on hand at the twelfth annual ideas summit (October 22-25 in Camden, Maine) to preview and discuss the themes in his forthcoming book The Outliers, which isn't the sequel to Chip Kidd's The Learners but an examination of what separates extraordinary and average people (hint: it involves memorable hair).

Other speakers in the just-announced line-up include social media guru Clay Shirky, MIT media lab researcher and huggable robot creator Kelly Dobson, and New York Times fragrance critic Chandler Burr, who earlier this year opined that an eau de Lever House would be "an angular blend of black currant, verbena, and grapefruit." For those who can't make it to Maine, Pop!Tech tells us that Yahoo! will again be live streaming the event in its entirety, free of charge, from October 23-25. Unfortunately for Burr fans, Yahoo! has yet to perfect Smell-o-vision.
