Twitter’s newest Board member once belonged to the C-suite of its much bigger competitor.

The social network announced Tuesday that Bret Taylor, former Facebook Chief Technology Officer and CEO of productivity software startup Quip, will join its board of directors as its ninth member. 

Taylor, who is also credited with co-creating Google Maps before joining Facebook, offers a product and engineering know-how the board largely lacks at the moment.

“Bret brings to our Board a great mind for consumer products and technologies that will be invaluable to the company as we execute our plans for 2016 and beyond,” said Twitter’s executive chairman, Omid Kordestani, in a press release statement.

Taylor is just the most recent of a string of high-profile board appointees overseen by Twitter CEO Jack Dorsey since taking back the company’s reins last year. 

Most recently, Twitter added some much-needed diversity to the group by bringing on BET (Black Entertainment Television) CEO and chairwoman Debra Lee as the board’s first black member.

Before that, in April, it added Pepsi chief financial officer and vice chairman Hugh Johnston and Internet entrepreneur Martha Lane Fox, finally ending the board’s notorious image as a “country club of old white guys,” as one Twitter investor put it. 

While Taylor, 35, doesn’t bring much to the table in terms of diversity, he at least seems well-versed in how to use the service, which more than can be said for some of Twitter’s board appointees — at least initially. He regularly tweets to his 42,000-some-odd followers.
