• Do we need to do a better job of making social entrepreneurship more understood in the mainstream? YouGov, a global opinion center, conducted a survey in the UK last year and discovered that only one-third of those surveyed could explain the definition of a social enterprise. Nearly fifty percent didn’t really understand the purpose of a social enterprise. While certainly not indicative for the entire world, the survey does suggest that the social enterprise sector could benefit with a little more mainstreaming, http://ht.ly/arw59

• Beverly Tam, a student at the University of California, San Diego, interview twelve female startup founders to understand the gap between the number of male and female founders. She discovered several common themes, including family, culture, and a lack of role models. Perhaps the most telling is a large aspiration gap—as Sheryl Sandberg says “until women are as ambitious as men, they’re not going to achieve as much as men.” See the full results of Beverly’s interviews and insights on what we can do to reduce the gap: http://ht.ly/arxn4

• David Brooks, a New York Times columnist, wrote an op-ed several days ago finding social entrepreneurs to be too idealistic and out of touch with ground realities. We have a different point of view. It’s the idealistic notion of what can be in this world that makes social changers so special. And, more than ever, social entrepreneurs are being required to deep dive into their impact and to prove their business models worthy of venture capital.
