Radian6 is helpful in locating target audiences by allowing the user to set a wide variety of preferences. This is hugely important to the interest of saving time.
Radian6 has evolved to display results in graphs that make it easy for viewers (at all levels) to interpret. This cuts down on the extra work you have to do in order to present your finidings to clients and/or executives.
Perhaps most useful, Radian6 quickly and accurately analyses trends. It really takes some of the guessing work out of crowd listening and allows the most up-to-date information to shine through the noise.
