"On balance, I suppose the privacy concerns about Facebook Dating are better grounded than concerns over competition.

Facebook Dating is now available in 20 countries, and can bootstrap its own growth by promoting itself in one of the most popular apps in the world — while further enmeshing itself with Instagram.
