Ask Dawn Henderson what most impresses her about Wharton’s efforts in social media, and her answer is quick and succinct: “Everything.”

Henderson, an Honours marketing student at the University of Strathglyde in Glasgow, Scotland, set out this year to analyze social media involvement of 20 top business schools in the United Kingdom and United States. And when Henderson finished her work, one thing was clear: Wharton is tops in tweeting.

And pretty much everything else in social media, too.

According to Henderson’s analysis, Wharton ranked far ahead of its peer schools. Harvard Business School and MIT’s Sloan School of Management were next best.

In her dissertation, Henderson wrote that Wharton “is clearly focused on engaging with prospective students, current students and their alumni, who all show a keen interest in interacting with the [the School] and adding to their student experience.”
