My Instagram followers want to know whether I like veggie chips and how many push-ups I can do in a row. The answer is no and one. On this week’s Why’d You Push That Button, Vox.com’s Kaitlyn Tiffany and I (Ashley Carman) discuss anonymous question-and-answer apps — why do people use them, both to ask and receive questions?First, I chat with my pal Vanessa about how they use Instagram’s question and answer feature to build community. Then, Kaitlyn chats with a minor Tumblr celebrity, Klaudia, about how she handles questions she’s asked and how she guides the youth of today through their lives. And finally, I interview Janis Grivins, the COO of Ask.fm, about why people ask anonymous questions and what purpose a masked identity can serve.
