Information is essential to all human activity and information in electronic form both
amplifies and augments human information interactions. This lecture surveys some of the
different classical meanings of information focuses on the ways that electronic technologies
are affecting how we think about these senses of information and introduces an emerging sense
of information that has implications for how we work play and interact with others. The
evolutions of computers and electronic networks and people's uses and adaptations of these
tools manifesting a dynamic space called cyberspace. Our traces of activity in cyberspace give
rise to a new sense of information as instantaneous identity states that I term proflection of
self. Proflections of self influence how others act toward us. Four classical senses of
information are described as context for this new form of information. The four senses selected
for inclusion here are the following: thought and memory communication process artifact and
energy. Human mental activity and state (thought and memory) have neurological cognitive and
affective facets.The act of informing (communication process) is considered from the
perspective of human intentionality and technical developments that have dramatically amplified
human communication capabilities. Information artifacts comprise a common sense of information
that gives rise to a variety of information industries. Energy is the most general sense of
information and is considered from the point of view of physical mental and social state
change. This sense includes information theory as a measurable reduction in uncertainty. This
lecture emphasizes how electronic representations have blurred media boundaries and added
computational behaviors that yield new forms of information interaction which in turn are
stored aggregated and mined to create profiles that represent our cyber identities. Table of
