Another way survey packages can make it easier to track different groups of respondents is via multiple "collector" links. These are simply different links to the same survey that can be broken out in analysis later. For example, if you wanted to field a survey to both Facebook and Twitter users, then posting different collector links on each network would let you track from which social network different respondents came.
