Longitudinal surveys are useful for studying the dynamics of a topic or issue over time.  However, samples tend to shrink over time (“mortality”), keeping track of subjects over time can be difficult, as can maintaining their interest in and willingness to participate in the study.  Thus, longitudinal surveys require an extended commitment on the part of the researcher, subjects, and all others involved.
