WeAreReading (regular live streams on KZfaq)
It's been said that Black people don't read. Well, I am building a comprehensive African-centred education library called #WeAreReading of in-depth and interactive studies into African Philosophy, African Culture and African History books. I cover books from authors like Amos Wilson, Marimba Ani, Oyeronke Oyewumi, Frantz Fanon, Sobonfu Some, Kwame Nkrumah and more. I stream live on KZfaq every weekend. After each live stream finishes, the full session is archived for patrons.

Any contributions I receive will be ploughed into these projects. My first aim is to simply cover costs - including web hosting, subscription to platforms I use, and maintaining and improving the hardware I use. Following this, I would like to reach a point where my work generates a level of income which will enable me to take time from my regular day job to increase the quality and quantity of content. Any contributions are welcome no matter the size, and no matter the frequency. Peace and blessings, Ely.
