Chances are you've tweeted more often than the latest addition to Twitter's executive ranks.
Twitter CEO Jack Dorsey announced Monday that Natalie Kerris, who most recently helped lead Apple's PR team, is the company's new VP of global communications. Kerris is taking on a role last held by Gabriel Stricker, who left Twitter last July after three years at the company. The new hire also comes on the heels of high-profile departures from Twitter last month.
