Tools are merely tools. They serve the purpose of supporting practices. They are a means to an end; not the end itself. However, tools, and their particular features, shape the way we do we do and perceive practices. For instance, an e-commerce platform provides an alternative way to shopping while new shopping practices inform the development of the said platform. A blog creates a new conduit of self and collective expression, and sometimes reflection. New features, as for example, embedding of video and photography, etc. are added to accommodate new forms of expression.. A Social Network Site can encourage alternative forms of congregation, as people made connections with people from different geographical areas with whom they have an affinity but whom they do not necessarily know personally.
As tools and practices influence one another, there is a need to reflect and revisit how we use these new conduits of communication; which practices we bring from other contexts, which ones we change, and which ones we discard.
Digital literacies encapsulate knowledge and know-how about how to use and perform in a mediated environment, in such a way that one is able to develop a reputable digital footprint; one that is able to represent herself/himself.
