The co-founder of Reddit just put the rest of the tech world on notice.

Alexis Ohanian announced Friday that he was resigning his Reddit board seat, and "urged" the rest of the board to fill his spot with a new black board member. He will also be donating all future gains on his Reddit stock to "serve the black community," and is immediately giving $1 million to Colin Kaepernick's racial justice charity.

Yes, take that in. Ohanian just set the bar for using power and privilege for racial equity by transferring not only resources, but also power to people of color.

The tech world has been looking for ways to support racial equality amid Black Lives Matter protests across the world. The leaders in efforts to promote diversity in tech say that one of the best ways tech leaders in particular can help is by investing in black businesses and venture funds, hiring black employees, and putting black people in positions of power within the tech world.

"Tech companies should be hiring [people of color] at all levels, from the board room to the boiler room," Rodney Sampson, a leader in tech diversity and founder of the accelerator OHUB, said. "If you’re a venture-backed tech company, you should be looking to put someone black on your board of advisors."

Ohanian called his move "long overdue." He explained that he had made his decision so that he could answer his black daughter (Ohanian's wife is Serena Williams) when she asked: "What did you do?"

Williams expressed support for her husband in a tweet that may have made this reporter choke up.

In the background of Ohanian's actions are the stark realities of Reddit, which Ohanian said he founded "to help people find community and a sense of belonging." Anyone who has spent even a passing moment on Reddit knows that it can be a quagmire of divisive vitriol. Amid the protests, some Reddit communities protested what they see as Reddit's failure to take stronger action against hate speech on the platform by making their communities private. Ellen Pao, a former VC, and one-time interim CEO of Reddit who now runs a tech diversity organization, called out Reddit's hypocrisy on Twitter:

There is, of course, no guarantee that Reddit leadership will take Ohanian up on his request to fill his seat with a black board member. But this is an opportunity to set an example for the rest of the tech and business world. Currently, around 11 percent of Fortune 100 board members are African American, according to a recent study by the Alliance for Board Diversity.

Mashable has reached out to Reddit to learn whether it intends to follow through with Ohanian's call to action, and Reddit said it would be responding "later today."
