Personally, I think the significance of Efem’s blog is to express her views through writing. She is trying to bring light to the racism and harsh opinions on the black community through her blog. Like it says in the story, she would interview random people she met on public transportation and get their opinions on what was going on in the world.
This is significant because they weren’t just her opinions they were the opinions of many people that she had met in her travels so they were real opinions and not just her own. This made the issues of racism more real in a sense that there were a ton of people acknowledging it.
