Bland, standard-issue profile of a (now) 26-year-old Internet entrepreneur.
Citing only previously published sources, the author retraces Karp’s rocketlike rise from disaffected student and teenage computer nerd to chief architect of Tumblr. Since he hasn’t really done much, aside from leaving school early, spending a few months in Japan and then making a zillion dollars since 2007 with his microblogging platform, the narrative is largely an eye-glazing tally of internships, business associates, awards and dizzying statistical milestones. Kenney neglects to analyze Tumblr’s innovations, online community or general context—or for that matter, even to explain the origins of “tumblelog,” from which the platform’s name is derived. Her insights into Karp’s character are limited to mentions of idols Steve Jobs (extolled for his “keynotes”) and Willy Wonka and his habit of carrying a paper notebook because “[being] on computers all the time makes me feel gross.” Many of the color photos are space-filler views of city skylines or the outsides of buildings.
Just another fabulously wealthy high school dropout role model. (endnotes, bibliography, index) (Biography. 10-13)
