Twitter turns 10 years old on Monday, marking a momentous milestone for a platform that has forever changed how we communicate in the 21st century.

The social network has impacted all kinds of people, but it's been especially significant for black users. This group, collectively known as Black Twitter, has used the platform to drive visibility to discussions about black life and culture, led by those who know it best.

In 140 characters, Black Twitter has helped reaffirm and redefine the black experience, as well as revolutionize the ways in which black people around the world can connect and collaborate.
