By default the Bio is collapsed. So I am supposed to follow people because of their gender, sexual orientation or disability, in order to have a more diverse Twitter feed?
That is some major virtue signalling right there. If that is how you define diversity for yourself you are mistaken. I can surround myself with 50 POC and 20 LGBTQ+ people and still gain no diversity of thoughts.
IMHO it would be far better if you handpicked people, asked them questions (short interview via Twitter) and then portrayed their profile on your website. Of course you should select users by some algorithm that optimally doesn't adhere to your pretty obvious political bias.
