Jesse Dangerously is a Canadian rapper who is generally placed in the "nerdcore" category, though he's much less blatant about it than, say,
MC Frontalot. He raps about things like technology, politics, and feminism; he has guest lectured at universities on the issue of gender roles in hip hop music. He also has a livejournal:
j_dangerouslyThe majority of his posts concern shows and appearances, but when he does put up an actual blog entry, it's generally intelligent, articulate, and insightful. I'm especially fond of two of his latest entries:
The first was posted today about how pop music tends to shape identity in American youth and how movies and other forms of media then use that to tap into our emotions and personal experiences.
The second is from a month ago, where he talks about Weird Al and the "White and Nerdy" phenomenon and how it relates to nerds, hip hop fans, and those people who had already bridged the two.
Check it out, yo.
