This Valentine’s Day, take a lesson from Cupid; he knows a thing or two about targeting. A person reached by his arrow and its sharp golden point is filled with uncontrollable desire. Cupid even sports wings because lovers (like coveted mobile users) are flighty and likely to change their minds. Armed with tools of the trade and clear on his targets, agile Cupid is ready to convert mere subjects into loyal, love-struck devotees.
