We make the NVDA screen reader which reads the PC for blind users. While we support the environment, #NVDA is almost universally known as the screen reader. I only worked out "Non-Violent Direct Action" when puzzling why someone tagged us in a previous post like this. Can I please convince you to trend #DirectAction instead? If we keep hashtags related to their topic, your followers can find info on protests while those looking for screen reader info can find that info. Good luck today
