From Brown University:
In the first scholarly research examining the role of black bloggers in the blogosphere, Brown University researcher Antoinette Pole assessed how bloggers of color use their medium for purposes related to politics. She found that black bloggers are, in fact, mobilizing readers to engage in political participation. Additionally, Pole found that black bloggers do not feel discriminated against or excluded by other bloggers.
Pole also found that black political bloggers do not necessarily blog about issues that are unique to minorities, though at times, they emphasize how issues affect blacks in particular. Respondents commonly reported writing about a variety of topics including race and ethnicity, party politics, and campaigns and elections.
