Why Blog? A direction.

So, why blog?  I guess that is the question.  Why are these groups spreading advocacy by advocating blogging?  This is not questioning citizen media or advocacy in and of itself.  I want to know why blogging is so important to these groups in this context in this discourse.  This analysis will require identifying blogging as a genre and identifying its conventions and analyzing the way in which meaning is created and presented in this form.  I guess part of this question has to ask if blogging in these colonial / post-colonial geographies.  This a geographically situated question as well.  But, what study about colonialism is not geographically situated?  So where does blogging fit in to those geographic regions, in these local discourse communities?  What is it doing to their agency in that community, in the larger region, and in the globalized colonial discourse?

Now, I need to come up with a proposal and analyze the relationship between these texts and these communities?  These communities are now producing these texts but is that because the text as a genre leads them to some sense of power, or is the power in the people and the text is merely a product of the discourse created by the community?
