  In this work we use the theory of Crowd Capital as a lens to compare and
contrast a number of IS tools currently in use by organizations for
crowd-engagement purposes. In doing so, we contribute to both the practitioner
and research domains. For the practitioner community we provide decision-makers
with a convenient and useful resource, in table-form, outlining in detail some
of the differing potentialities of crowd-engaging IS. For the research
community we begin to unpack some of the key properties of crowd-engaging IS,
including some of the differing qualities of the crowds that these IS
application engage.
