There has been no official word, as yet, as to why this decision was made, and specifically by whom. Although one tidbit of information I do know in how these profiles will be utilized, is that each profile will be linked to the person's personal content on LDS.org via a system known as Google authorship markup. The way I understand how this works, is that when Google returns search results of a particular author whose content is 'connected' in this manner, a photo will appear next to the result; pretty cool!
Thomas S. Monson, Henry B. Eyring, and, Dieter F. Uchtdorf the three highest officials in The Church of Jesus Christ of Latter-day Saints, constituting the First Presidency of the Church, have taken an unprecedented and significant step to broaden their public outreach. The LDS Church have launched individual profiles for each of the three spiritual leaders, considered by Mormons to be living prophets upon the earth today, on Google Plus -- a popular social network, similar to Facebook.
